Added a proc macro to be able to write XCMs using the builder pattern.
This means we go from having to do this:

```rust
let message: Xcm<()> = Xcm(vec![
  WithdrawAsset(assets),
  BuyExecution { fees: asset, weight_limit: Unlimited },
  DepositAsset { assets, beneficiary },
]);
```

to this:

```rust
let message: Xcm<()> = Xcm::builder()
  .withdraw_asset(assets)
  .buy_execution(asset, Unlimited),
  .deposit_asset(assets, beneficiary)
  .build();
```

When running with `--relay-chain-rpc-url` we received multiple reports
of high traffic that disappears when `--in-peers-light 0` is set. Indeed
it does not make much sense for light clients to connect to the minimal
node since it is not running the block announce protocol and the
request/response protocol for light clients.

This is intended to alleviate the traffic issues for now.

### Problem
Quoting from the above issue:

> When adding a pallet to chain after genesis we currently don't set the
StorageVersion. So, when calling on_chain_storage_version it returns 0
while the pallet is maybe already at storage version 9 when it was added
to the chain. This could lead to issues when running migrations.

### Solution

- Create a new trait `BeforeAllRuntimeMigrations` with a single method
`fn before_all_runtime_migrations() -> Weight` trait with a noop default
implementation
- Modify `Executive` to call
`BeforeAllRuntimeMigrations::before_all_runtime_migrations` for all
pallets before running any other hooks
- Implement `BeforeAllRuntimeMigrations` in the pallet proc macro to
initialize the on-chain version to the current pallet version if the
pallet has no storage set (indicating it has been recently added to the
runtime and needs to have its version initialised).

### Other changes in this PR

- Abstracted repeated boilerplate to access the `pallet_name` in the
pallet expand proc macro.

### FAQ

#### Why create a new hook instead of adding this logic to the pallet
`pre_upgrade`?

`Executive` currently runs `COnRuntimeUpgrade` (custom migrations)
before `AllPalletsWithSystem` migrations. We need versions to be
initialized before the `COnRuntimeUpgrade` migrations are run, because
`COnRuntimeUpgrade` migrations may use the on-chain version for critical
logic. e.g. `VersionedRuntimeUpgrade` uses it to decide whether or not
to execute.

We cannot reorder `COnRuntimeUpgrade` and `AllPalletsWithSystem` so
`AllPalletsWithSystem` runs first, because `AllPalletsWithSystem` have
some logic in their `post_upgrade` hooks to verify that the on-chain
version and current pallet version match. A common use case of
`COnRuntimeUpgrade` migrations is to perform a migration which will
result in the versions matching, so if they were reordered these
`post_upgrade` checks would fail.

#### Why init the on-chain version for pallets without a current storage
version?

We must init the on-chain version for pallets even if they don't have a
defined storage version so if there is a future version bump, the
on-chain version is not automatically set to that new version without a
proper migration.

e.g. bad scenario:

1. A pallet with no 'current version' is added to the runtime
2. Later, the pallet is upgraded with the 'current version' getting set
to 1 and a migration is added to Executive Migrations to migrate the
storage from 0 to 1
    a. Runtime upgrade occurs
    b. `before_all` hook initializes the on-chain version to 1
c. `on_runtime_upgrade` of the migration executes, and sees the on-chain
version is already 1 therefore think storage is already migrated and
does not execute the storage migration
Now, on-chain version is 1 but storage is still at version 0.

By always initializing the on-chain version when the pallet is added to
the runtime we avoid that scenario.

Add infrastructure needed to have a Pallet::decode_entire_state(), which
makes sure all "typed" storage items defined in the pallet are
decode-able.

This is not enforced in any way at the moment. Teams who wish to
integrate/use this in the try-runtime feature flag should add
frame_support::storage::migration::EnsureStateDecodes as the LAST ITEM
of the runtime's custom migrations, and pass it to frame-executive. This
will make it usable in try-runtime on-runtime-upgrade.

This now catches cases like

This PR will upgrade the network protocol to version 3 -> VStaging which

Instead of issuing/importing one tranche0 assignment per candidate,
there will be just one certificate per relay chain block per validator.
However, we will not be sending out the new assignment certificates,

> ensure through proper configuration that the new byte-based deposit is

Not sure this is needed anymore. If the new deposits are higher than
what is currently on chain and users don't have enough funds to reserve
what is needed, the extrinisc fails and they're basically grandfathered
and frozen until they add more funds and/or make a change to their
identity. This behavior seems fine to me. Original idea
[here](https://github.com/paritytech/polkadot-sdk/pull/1661#issuecomment-1779606319).

The `BlockBuilderProvider` was a trait that was defined in
`sc-block-builder`. The trait was implemented for `Client`. This
basically meant that you needed to import `sc-block-builder` any way to
have access to the block builder. So, this trait was not providing any
real value. This pull request is removing the said trait. Instead of the
trait it introduces a builder for creating a `BlockBuilder`. The builder
currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
any better name 😅

). The rest of the pull request is about
replacing the old trait with the new builder.

# Downstream code changes

If you used `new_block` or `new_block_at` before you now need to switch
it over to the new `BlockBuilderBuilder` pattern:

```rust
// `new` requires a type that implements `CallApiAt`. 
let mut block_builder = BlockBuilderBuilder::new(client)
                // Then you need to specify the hash of the parent block the block will be build on top of
		.on_parent_block(at)
                // The block builder also needs the block number of the parent block. 
                // Here it is fetched from the given `client` using the `HeaderBackend`
                // However, there also exists `with_parent_block_number` for directly passing the number
		.fetch_parent_block_number(client)
		.unwrap()
                // Enable proof recording if required. This call is optional.
		.enable_proof_recording()
                // Pass the digests. This call is optional.
                .with_inherent_digests(digests)

Added if condition on review-bot's trigger so it does not trigger in
`draft` PRs.

Right now governance could only control byte-fee component of Rococo <>
Westend message fees (paid at Asset Hubs). This PR changes it a bit:
1) governance now allowed to control both fee components - byte fee and
base fee;
2) base fee now includes cost of "default" delivery and confirmation
transactions, in addition to `ExportMessage` instruction cost.

- This adds the new trait `StorageDecodeNonDedupLength` and implements
them for `BTreeSet` and its bounded types.
- New unit test has been added to cover the case.  
- See linked
[issue](https://github.com/paritytech/polkadot-sdk/issues/126) which
outlines the original issue.

Note that the added trait here doesn't add new logic but improves
semantics.

(imported from https://github.com/paritytech/cumulus/pull/2157)

## Changes

This MR refactores the XCMP, Parachains System and DMP pallets to use
the [MessageQueue](https://github.com/paritytech/substrate/pull/12485)
for delayed execution of incoming messages. The DMP pallet is entirely
replaced by the MQ and thereby removed. This allows for PoV-bounded
execution and resolves a number of issues that stem from the current
work-around.

All System Parachains adopt this change.  
The most important changes are in `primitives/core/src/lib.rs`,
`parachains/common/src/process_xcm_message.rs`,
`pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs`
and the runtime configs.

### DMP Queue Pallet

The pallet got removed and its logic refactored into parachain-system.
Overweight message management can be done directly through the MQ
pallet.

Final undeployment migrations are provided by
`cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that
can be configured with an aux config trait like:

```rust
parameter_types! {
	pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME;
	pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent;
}

impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime {
	type PalletName = DmpQueuePalletName;
	type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>;
	type DbWeight = <Runtime as frame_system::Config>::DbWeight;
}

// And adding them to your Migrations tuple:
pub type Migrations = (
	...
	cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>,
	cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>,
);
```

### XCMP Queue pallet

Removed all dispatch queue functionality. Incoming XCMP messages are now
either: Immediately handled if they are Signals, enqueued into the MQ
pallet otherwise.

New config items for the XCMP queue pallet:
```rust
/// The actual queue implementation that retains the messages for later processing.
type XcmpQueue: EnqueueMessage<ParaId>;

/// How a XCM over HRMP from a sibling parachain should be processed.
type XcmpProcessor: ProcessMessage<Origin = ParaId>;

/// The maximal number of suspended XCMP channels at the same time.
#[pallet::constant]
type MaxInboundSuspended: Get<u32>;
```

How to configure those:

```rust
// Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since
// the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s.
type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>;

// Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched
// with origin `Junction::Sibling(…)`.
type XcmpProcessor = ProcessFromSibling<
	ProcessXcmMessage<
		AggregateMessageOrigin,
		xcm_executor::XcmExecutor<xcm_config::XcmConfig>,
		RuntimeCall,
	>,
>;

// Not really important what to choose here. Just something larger than the maximal number of channels.
type MaxInboundSuspended = sp_core::ConstU32<1_000>;
```

The `InboundXcmpStatus` storage item was replaced by
`InboundXcmpSuspended` since it now only tracks inbound queue suspension
and no message indices anymore.

Now only sends the most recent channel `Signals`, as all prio ones are
out-dated anyway.

### Parachain System pallet

For `DMP` messages instead of forwarding them to the `DMP` pallet, it
now pushes them to the configured `DmpQueue`. The message processing
which was triggered in `set_validation_data` is now being done by the MQ
pallet `on_initialize`.

XCMP messages are still handed off to the `XcmpMessageHandler`
(XCMP-Queue pallet) - no change here.

New config items for the parachain system pallet:
```rust
/// Queues inbound downward messages for delayed processing. 
///
/// Analogous to the `XcmpQueue` of the XCMP queue pallet.
type DmpQueue: EnqueueMessage<AggregateMessageOrigin>;
``` 

How to configure:
```rust
/// Use the MQ pallet to store DMP messages for delayed processing.
type DmpQueue = MessageQueue;
``` 

## Message Flow

The flow of messages on the parachain side. Messages come in from the
left via the `Validation Data` and finally end up at the `Xcm Executor`
on the right.

## Further changes

- Bumped the default suspension, drop and resume thresholds in
`QueueConfigData::default()`.
- `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when
they would be a noop.
- Properly validate the `QueueConfigData` before setting it.
- Marked weight files as auto-generated so they wont auto-expand in the
MR files view.
- Move the `hypothetical` asserts to `frame_support` under the name
`experimental_hypothetically`

Questions:
- [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in
the runtimes? Not sure how to best fix. Just having them like this makes
tests fail that rely on the real message processor when the feature is
enabled.
- [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler
already takes 80% so I put it to 10% but that is quite low.

Fixes https://github.com/paritytech/polkadot-sdk/issues/2123

# Description
We derive few useful traits on `ErrorOrigin` and `ExecError`, including
`codec::Encode` and `codec::Decode`, so that `ExecResult` is
en/decodable as well. This is required for a contract mocking feature
(already prepared in drink:
https://github.com/Cardinal-Cryptography/drink/pull/61). In more detail:
`ExecResult` must be passed from runtime extension, through runtime
interface, back to the pallet, which requires that it is serializable to
bytes in some form (or implements some rare, auxiliary traits).

**Impact on runtime size**: Since most of these traits is used directly
in the pallet now, compiler should be able to throw it out (and thus we
bring no new overhead). However, they are very useful in secondary tools
like drink or other testing libraries.
