Various pallet-revive improvements

- add check for precompiles addresses,
So we can easily identify which one are being called and not supported
yet

- fixes debug_call for revert call
If a call revert we still want to get the traces for that call, that
matches geth behaviors, diff tests will be added to the test suite for
this

- fixes traces for staticcall
The call type was not always being reported properly.

We mainly need that so that we can finally compile the `pallet_revive`
fixtures on stable. I did my best to keep the commits focused on one
thing to make review easier.

All the changes are needed because rustc introduced more warnings or is
more strict about existing ones. Most of the stuff could just be fixed
and the commits should be pretty self explanatory. However, there are a
few this that are notable:

## `non_local_definitions `

A lot of runtimes to write `impl` blocks inside functions. This makes
sense to reduce the amount of conditional compilation. I guess I could
have moved them into a module instead. But I think allowing it here
makes sense to avoid the code churn.

## `unexpected_cfgs`

The FRAME macros emit code that references various features like `std`,
`runtime-benchmarks` or `try-runtime`. If a create that uses those
macros does not have those features we get this warning. Those were
mostly when defining a `mock` runtime. I opted for silencing the warning
in this case rather than adding not needed features.

For the benchmarking ui tests I opted for adding the `runtime-benchmark`
feature to the `Cargo.toml`.

## Failing UI test

I am bumping the `trybuild` version and regenerating the ui tests. The
old version seems to be incompatible. This requires us to pass
`deny_warnings` in `CARGO_ENCODED_RUSTFLAGS` as `RUSTFLAGS` is ignored
in the new version.

## Removing toolchain file from the pallet revive fixtures

This is no longer needed since the latest stable will compile them fine
using the `RUSTC_BOOTSTRAP=1`.

Pallet-revive's README has an outdated link for dispatchables
documentation in its README. It was giving 404. Put the up-to-date one.

This PR adds a new stable branch `stable2503` to the backport CI

Add the sudo pallet to coretime-westend, allowing use in
development/testing. Previously the coretime-rococo runtime was used in
situations like this, but since Rococo is now gone this can be used
instead.

No sudo key is added to Westend storage with this PR, since it's likely
that any updates will continue to be done over XCM. If this is something
that is wanted the key can be set via XCM.

## Review Notes

Mentorship is requested to ensure this is implemented correctly.

The lease is removed from state using the TaskId as a key. Is this

#### Overview

This pull request refactors the transaction pool `graph` module by
renaming components for better clarity. The `EventHandler` trait was
introduced to enhance flexibility in handling transaction lifecycle
events. Changes include renaming `graph::Listener` to
`graph::EventDispatcher` and moving certain functionalities from `graph`
to `view` module in order to decouple `graph` from `view`-related
specifics.

This PR does not introduce changes in the logic.

#### Notes for Reviewers
All the changes looks dense at first, but in fact following was done:
- The `graph::Listener` was renamed to
[`graph::EventDispatcher`](https://github.com/paritytech/polkadot-sdk/blob/515cb404/substrate/client/transaction-pool/src/graph/listener.rs#L74C12-L74C27),
to better reflect its role in dispatching transaction-related events
from `ValidatedPool`. The `EventDispatcher` now utilizes the `L:
EventHandler` generic type to handle transaction status events.
- The new
[`EventHandler`](https://github.com/paritytech/polkadot-sdk/blob/515cb404/substrate/client/transaction-pool/src/graph/listener.rs#L34)
trait was introduced to handle transaction lifecycle events, improving
implementation flexibility and providing clearer role descriptions
within the system. Introduction of this trait allowed the removal of
`View` related entities (e.g. streams) from the `ValidatedPool`'s event
dispatcher (previously _listener_).
- The _dropped monitoring_ and _aggregated events_ stream
[functionalities](https://github.com/paritytech/polkadot-sdk/blob/515cb404/substrate/client/transaction-pool/src/fork_aware_txpool/view.rs#L157-L188)
and [related
types](https://github.com/paritytech/polkadot-sdk/blob/515cb404/substrate/client/transaction-pool/src/fork_aware_txpool/view.rs#L112-L121)
were moved from `graph::listener` to the `view` module. The
[`ViewPoolObserver`](https://github.com/paritytech/polkadot-sdk/blob/515cb404

/substrate/client/transaction-pool/src/fork_aware_txpool/view.rs#L128C19-L128C35),
which implements `EventHandler`, now provides the implementation of
streams feeding.
- Fields, arguments, and variables previously named `listener` were
renamed to `event_dispatcher` to align with their purpose and type
naming.
- Various structs such as `Pool` and `ValidatedPool` were updated to
include a generic `L: EventHandler` across the codebase.

## Description

The PR enhances the `pallet-bridge-rewards` by making it generic over
the `RewardKind` type (previously hardcoded as `RewardsAccountParams`).
This modification allows the pallet to support multiple reward types
(e.g., P/K bridge, Snowbridge), increasing its flexibility and
applicability across various bridge scenarios.

Other pallets can register rewards using `bp_relayers::RewardLedger`,
which is implemented by the rewards pallet. The runtime can then be
configured with different mechanisms for paying/claiming rewards via
`bp_relayers::PaymentProcedure` (e.g., see the `pub struct
BridgeRewardPayer;` implementation for BridgeHubWestend).

## Follow-up  
The removed balances/rewards statistics from the complex relay (no
longer used) will eventually be reintroduced or fixed in the standalone
relayers via
https://github.com/paritytech/parity-bridges-common/issues/3004#issuecomment-2401634589.

XCM: Deny barrier checks for nested XCMs with specific instructions to be executed on the local chain (#7200)

Resolves (partially):
https://github.com/paritytech/polkadot-sdk/issues/7148
Depends on: https://github.com/paritytech/polkadot-sdk/pull/7169

# Description

This PR addresses partially #7148 (Problem 2) and ensures the proper
checking of nested local instructions. It introduces a new barrier -
`DenyRecursively` - to provide more refined control over instruction
denial. The main change is the replacement of `DenyThenTry<Deny, Allow>`
with `DenyThenTry<DenyRecursively<Deny>, Allow>` which handles both
top-level and nested local instructions by applying allow condition
after denial.

For context and additional information, please refer to [_Problem 2 -
Barrier vs nested XCM
validation_](https://github.com/paritytech/polkadot-sdk/issues/7148).

# TODO
- [x] Evaluate PoC, more details at #7351:
    - **DenyNestedXcmInstructions**: Keep it as it is and be explicit:
        1. Name the Deny barriers for the top level.
2. Name the Deny barrier for nested with `DenyInstructionsWithXcm`.
- **DenyThenTry<DenyInstructionsWithXcm<Deny>, Allow>**: Alternatively,
hard-code those three instructions in `DenyThenTry`, so we wouldn’t need
`DenyInstructionsWithXcm`. However, this approach wouldn’t be as
general.
- **DenyInstructionsWithXcmFor**: Another possibility is to check
`DenyInstructionsWithXcm::Inner` for the actual `message`, so we don’t
need duplication for top-level and nested (not sure, maybe be explicit
is good thing) - see _Problem2 - example_. Instead of this:
   ```
  DenyThenTry<
                (
                               // Deny for top level XCM program 
                               DenyReserveTransferToRelayChain,
// Dedicated barrier for nested XCM programs
                               DenyInstructionsWithXcmFor<
// Repeat all Deny filters here
DenyReserveTransferToRelayChain,
                                >
                ),
   ```
  we could just use:
   ```
  DenyThenTry<
                (
                               // Dedicated barrier for XCM programs
                               DenyInstructionsWithXcmFor<
// Add all `Deny` filters here
DenyReserveTransferToRelayChain,
                                                ...
                                >
                ),
   ```
- [POC

This PR implements `DecodeWithMemTracking` for the types in the frame
pallets

The PR is verbose, but it's very simple. `DecodeWithMemTracking` is
simply derived for most of the types. There are only 3 exceptions which
are isolated into 2 separate commits.

PR adds a resuable workflow that prevents CI to run on draft PRs. To run
CI on draft a new label is introduced: `A5-run-CI`. To run the CI the
label should be added and en empty commit should be pushed.

Fix issue where setting the `remote_fees` field of `InitiateTransfer` to
`None` could lead to unintended bypassing of fees in certain conditions.

Changes made to fix this:
- `remote_fees: None` now results in the `UnpaidExecution` instruction
being appended *after* the origin altering instruction, be it
`AliasOrigin` or `ClearOrigin`. This means `preserve_origin: true` must
be set if you want to have any chance of not paying for fees.
- The `AliasOrigin` instruction is not appended if the executor is
called with the root location (`Here`) since it would alias to itself.
Although this self-aliasing could be done, it needs the ecosystem to add
a new aliasing instruction, so we just skip it.
- Tweaked the `AllowExplicitUnpaidExecutionFrom` barrier to allow
receiving assets (via teleport or reserve asset transfer) and altering
the origin before actually using `UnpaidExecution`. This is to allow
unpaid teleports to work with `InitiateTransfer`.
- For this, the barrier now executes origin altering instructions and
keeps track of the modified origin. It then checks if this final origin
has enough permissions to not pay for fees. In order to follow the
`AliasOrigin` instruction it now takes a new generic `Aliasers` that
should be set to the XCM config item of the same name. This new generic
has a default value of `()`, effectively disallowing the use of
`AliasOrigin`.

Recreation of https://github.com/paritytech/polkadot-sdk/pull/7357 on
top of master. The old PR messes up the git history too much so I am
recreating it from scratch.

This PR is work in progress. It's purpose is to commit initial structure
of `pallet-staking-ah-client` and `pallet-staking-rc-client` to master.
The changes will be polished by a follow up PRs which will be
backported.

Related issues: https://github.com/paritytech/polkadot-sdk/issues/6167
and https://github.com/paritytech/polkadot-sdk/issues/6166

This PR introduces the initial structure for `pallet-ah-client` and
`pallet-rc-client`. These pallets will reside on the relay chain and
AssetHub, respectively, and will manage the interaction between
`pallet-session` on the relay chain and `pallet-staking` on AssetHub.

Both pallets are experimental and not intended for production use.

- [ ] Probably handle

closes https://github.com/paritytech/polkadot-sdk/issues/3610.

helps https://github.com/paritytech/polkadot-sdk/issues/6344, but need
to migrate storage `Offences::Reports` before we can remove exposure
dependency in RC pallets.

replaces https://github.com/paritytech/polkadot-sdk/issues/6788.

## Context  
Slashing in staking is unbounded currently, which is a major blocker
until staking can move to a parachain (AH).

### Current Slashing Process (Unbounded)  

1. **Offence Reported**  
- Offences include multiple validators, each with potentially large
exposure pages.
- Slashes are **computed immediately** and scheduled for application
after **28 eras**.

2. **Slash Applied**  
- All unapplied slashes are executed in **one block** at the start of
the **28th era**. This is an **unbounded operation**.


### Proposed Slashing Process (Bounded)  

1. **Offence Queueing**  
   - Offences are **queued** after basic sanity checks.  

2. **Paged Offence Processing (Computing Slash)**  
   - Slashes are **computed one validator exposure page at a time**.  
   - **Unapplied slashes** are stored in a **double map**:  
     - **Key 1 (k1):** `EraIndex`  
- **Key 2 (k2):** `(Validator, SlashFraction, PageIndex)` — a unique
identifier for each slash page

3. **Paged Slash Application**  
- Slashes are **applied one page at a time** across multiple blocks.
- Slash application starts at the **27th era** (one era earlier than
before) to ensure all slashes are applied **before stakers can unbond**
(which starts from era 28 onwards).

---

## Worst-Case Block Calculation for Slash Application  

### Polkadot:  
- **1 era = 24 hours**, **1 block = 6s** → **14,400 blocks/era**  
- On parachains (**12s blocks**) → **7,200 blocks/era**  

### Kusama:  
- **1 era = 6 hours**, **1 block = 6s** → **3,600 blocks/era**  
- On parachains (**12s blocks**) → **1,800 blocks/era**  

### Worst-Case Assumptions:  
- **Total stakers:** 40,000 nominators, 1000 validators. (Polkadot
currently has ~23k nominators and 500 validators)
- **Max slashed:** 50% so 20k nominators, 250 validators.  
- **Page size:** Validators with multiple page: (512 + 1)/2 = 256 ,
Validators with single page: 1

### Calculation:  
There might be a more accurate way to calculate this worst-case number,
and this estimate could be significantly higher than necessary, but it
shouldn’t exceed this value.

Blocks needed: 250 + 20k/256 = ~330 blocks.

##  *Potential Improvement:*  
- Consider adding an **Offchain Worker (OCW)** task to further optimize
slash application in future updates.
- Dynamically batch unapplied slashes based on number of nominators in
the page, or process until reserved weight limit is exhausted.

----
## Summary of Changes  

### Storage  
- **New:**  
  - `OffenceQueue` *(StorageDoubleMap)*  
    - **K1:** Era  
    - **K2:** Offending validator account  
    - **V:** `OffenceRecord`  
  - `OffenceQueueEras` *(StorageValue)*  
    - **V:** `BoundedVec<EraIndex, BoundingDuration>`  
  - `ProcessingOffence` *(StorageValue)*  
    - **V:** `(Era, offending validator account, OffenceRecord)`  

- **Changed:**  
  - `UnappliedSlashes`:  
    - **Old:** `StorageMap<K -> Era, V -> Vec<UnappliedSlash>>`  
- **New:** `StorageDoubleMap<K1 -> Era, K2 -> (validator_acc, perbill,
page_index), V -> UnappliedSlash>`

### Events  
- **New:**  
  - `SlashComputed { offence_era, slash_era, offender, page }`  
  - `SlashCancelled { slash_era, slash_key, payout }`  

### Error  
- **Changed:**  
  - `InvalidSlashIndex` → Renamed to `InvalidSlashRecord`  
- **Removed:**  
  - `NotSortedAndUnique`  
- **Added:**  
  - `EraNotStarted`  

### Call  
- **Changed:**  
  - `cancel_deferred_slash(era, slash_indices: Vec<u32>)`  
    → Now takes `Vec<(validator_acc, slash_fraction, page_index)>`  
- **New:**  
- `apply_slash(slash_era, slash_key: (validator_acc, slash_fraction,
page_index))`

### Runtime Config  
- `FullIdentification` is now set to a unit type (`()`) / null identity,
replacing the previous exposure type for all runtimes using
`pallet_session::historical`.

## TODO
- [x] Fixed broken `CancelDeferredSlashes`.
- [x] Ensure on_offence called only with validator account for
identification everywhere.
- [ ] Ensure we never need to read full exposure.
- [x] Tests for multi block processing and application of slash.
- [x] Migrate UnappliedSlashes 
- [x] Bench (crude, needs proper bench as followup)
  - [x] on_offence()
  - [x] process_offence()
  - [x] apply_slash()
 
 
## Followups (tracker
[link](https://github.com/paritytech/polkadot-sdk/issues/7596))
- [ ] OCW task to process offence + apply slashes.
- [ ] Minimum time for governance to cancel deferred slash.
- [ ] Allow root or staking admin to add a custom slash.
- [ ] Test HistoricalSession proof works fine with eras before removing
exposure as full identity.
- [ ] Properly bench offence processing and slashing.
- [ ] Handle Offences::Reports migration when removing validator
exposure as identity.

Add emulated e2e tests for following scenarios:

Exporting native asset to another ecosystem:
- Sending WNDs from Penpal Westend to Penpal Rococo: PPW->AHW->AHR->PPR
- Sending WNDs from Westend Relay to Penpal Rococo: W->AHW->AHR->PPR
   Example: Westend Treasury funds something on Rococo Parachain.

Importing native asset from another ecosystem to its native ecosystem:
- Sending ROCs from Penpal Westend to Penpal Rococo: PPW->AHW->AHR->PPR
- Sending ROCs from Penpal Westend to Rococo Relay: PPW->AHW->AHR->R
   Example: Westend Parachain returns some funds to Rococo Treasury.

This PR modifies the libp2p networking-specific log targets for granular
control (e.g., just enabling trace for req-resp).

Previously, all logs were outputted to `sub-libp2p` target, flooding the
log messages on busy validators.

### Changes
- Discover: `sub-libp2p::discovery`
- Notification/behaviour: `sub-libp2p::notification::behaviour`
- Notification/handler: `sub-libp2p::notification::handler`
- Notification/service: `sub-libp2p::notification::service`
- Notification/upgrade: `sub-libp2p::notification::upgrade`
- Request response: `sub-libp2p::request-response`

Returning an iterator in `TracksInfo::tracks()` instead of a static
slice allows for more flexible implementations of `TracksInfo` that can
use the chain storage without compromising a lot on the
performance/memory penalty if we were to return an owned `Vec` instead.

# Utility Call Fallback

This introduces a new extrinsic: **`if_else`**

Which first attempts to dispatch the `main` call(s). If the `main`
call(s) fail, the `fallback` call(s) is dispatched instead. Both calls
are executed with the same origin.

In the event of a fallback failure the whole call fails with the weights
returned.

## Use Case
Some use cases might involve submitting a `batch` type call in either
main, fallback or both.

Resolves #6000
