Changes:
- Add pallet-parameters to Rococo to configure the NIS and preimage
pallet.
- Fix names of expanded dynamic params. Apparently, `to_class_case`
removes suffix `s`, and `Nis` becomes `Ni` 😑

. Now using
`to_pascal_case`.

This PR introduces `BlockHashProvider` into `pallet_mmr::Config`
This type is used to get `block_hash` for a given `block_number` rather
than directly using `frame_system::Pallet::block_hash`

The `DefaultBlockHashProvider` uses `frame_system::Pallet::block_hash`
to get the `block_hash`

Closes: #4062

This PR mainly removes `xcm::v3` stuff from `assets-common` to make it
more generic and facilitate the transition to newer XCM versions. Some
of the implementations here used hard-coded `xcm::v3::Location`, but now
it's up to the runtime to configure according to its needs.

Additional/consequent changes:
- `penpal` runtime uses now `xcm::latest::Location` for `pallet_assets`
as `AssetId`, because we don't care about migrations here
- it pretty much simplify xcm-emulator integration tests, where we don't
need now a lots of boilerplate conversions:
      ```
      v3::Location::try_from(...).expect("conversion works")`
      ```
- xcm-emulator tests
- split macro `impl_assets_helpers_for_parachain` to the
`impl_assets_helpers_for_parachain` and
`impl_foreign_assets_helpers_for_parachain` (avoids using hard-coded
`xcm::v3::Location`)

1. The `CustomFmtContext::ContextWithFormatFields` enum arm isn't
actually used and thus we don't need the enum anymore.

2. We don't do anything with most of the normalized metadata that's
created by calling `event.normalized_metadata();` - the `target` we can
get from `event.metadata.target()` and level we can get from
`event.metadata.level()` - let's just call them direct to simplify
things. (`event.metadata()` is just a field call under the hood)

Changelog: No functional changes, might run a tad faster with lots of
logging turned on.

### What's inside

A job, that will take each of the three
[templates](https://github.com/paritytech/polkadot-sdk/tree/master/templates),
yank them out of the monorepo workspace, and push to individual
repositories
([1](https://github.com/paritytech/polkadot-sdk-minimal-template),
[2](https://github.com/paritytech/polkadot-sdk-parachain-template),
[3](https://github.com/paritytech/polkadot-sdk-solochain-template)).

In case the build/test does not succeed, a PR such as [this
one](https://github.com/paritytech-stg/polkadot-sdk-solochain-template/pull/2)
gets created instead.

I'm proposing a manual dispatch trigger for now - so we can test and
iterate faster - and change it to fully automatic triggered by releases
later.

The manual trigger looks like this:

<img width="340px"
src="https://github.com/paritytech/polkadot-sdk/assets/12039224/e87e0fda-23a3-4735-9035-af801e8417fc"/>

### How it works

The job replaces dependencies [referenced by
git](https://github.com/paritytech/polkadot-sdk/blob/d733c77e/templates/minimal/pallets/template/Cargo.toml#L25)
with a reference to released crates using
[psvm](https://github.com/paritytech/psvm).

It creates a new workspace for the template, and adapts what's needed
from the `polkadot-sdk` workspace.

### See the results

The action has been tried out in staging, and the results can be
observed here:

- [minimal
stg](https://github.com/paritytech-stg/polkadot-sdk-minimal-template/)
- [parachain
stg](https://github.com/paritytech-stg/polkadot-sdk-parachain-template/)
- [solochain
stg](https://github.com/paritytech-stg/polkadot-sdk-solochain-template/)

These are based on the `1.9.0` release (using `release-crates-io-v1.9.0`
branch).

# Description

Add `transfer_assets_using()` for transferring assets from local chain
to destination chain using explicit XCM transfer types such as:
- `TransferType::LocalReserve`: transfer assets to sovereign account of
destination chain and forward a notification XCM to `dest` to mint and
deposit reserve-based assets to `beneficiary`.
- `TransferType::DestinationReserve`: burn local assets and forward a
notification to `dest` chain to withdraw the reserve assets from this
chain's sovereign account and deposit them to `beneficiary`.
- `TransferType::RemoteReserve(reserve)`: burn local assets, forward XCM
to `reserve` chain to move reserves from this chain's SA to `dest`
chain's SA, and forward another XCM to `dest` to mint and deposit
reserve-based assets to `beneficiary`. Typically the remote `reserve` is
Asset Hub.
- `TransferType::Teleport`: burn local assets and forward XCM to `dest`
chain to mint/teleport assets and deposit them to `beneficiary`.

By default, an asset's reserve is its origin chain. But sometimes we may
want to explicitly use another chain as reserve (as long as allowed by
runtime `IsReserve` filter).

This is very helpful for transferring assets with multiple configured
reserves (such as Asset Hub ForeignAssets), when the transfer strictly
depends on the used reserve.

E.g. For transferring Foreign Assets over a bridge, Asset Hub must be
used as the reserve location.

# Example usage scenarios

## Transfer bridged ethereum ERC20-tokenX between ecosystem parachains.

ERC20-tokenX is registered on AssetHub as a ForeignAsset by the
Polkadot<>Ethereum bridge (Snowbridge). Its asset_id is something like
`(parents:2, (GlobalConsensus(Ethereum), Address(tokenX_contract)))`.
Its _original_ reserve is Ethereum (only we can't use Ethereum as a
reserve in local transfers); but, since tokenX is also registered on
AssetHub as a ForeignAsset, we can use AssetHub as a reserve.

With this PR we can transfer tokenX from ParaA to ParaB while using
AssetHub as a reserve.

## Transfer AssetHub ForeignAssets between parachains

AssetA created on ParaA but also registered as foreign asset on Asset
Hub. Can use AssetHub as a reserve.

And all of the above can be done while still controlling transfer type
for `fees` so mixing assets in same transfer is supported.

# Tests

Added integration tests for showcasing:
- transferring local (not bridged) assets from parachain over bridge
using local Asset Hub reserve,
- transferring foreign assets from parachain to Asset Hub,
- transferring foreign assets from Asset Hub to parachain,
- transferring foreign assets from parachain to parachain using local
Asset Hub reserve.

Completes the removal of `try-runtime-cli` logic from `polkadot-sdk`.

Implements the idea from
https://github.com/paritytech/polkadot-sdk/pull/3899
- Removed latencies
- Number of runs reduced from 50 to 5, according to local runs it's
quite enough
- Network message is always sent in a spawned task, even if latency is
zero. Without it, CPU time sometimes spikes.
- Removed the `testnet` profile because we probably don't need that
debug additions.

After the local tests I can't say that it brings a significant
improvement in the stability of the results. However, I belive it is
worth trying and looking at the results over time.

Currently `subsystem-regression-tests` job fails if the first benchmarks
fail and there is no result for the second benchmark. Also dividing the
job makes the pipeline faster (currently it's a longest job)

This is phase 2 of async backing enablement for the system parachains on
the production networks. ~~It should be merged after
polkadot-fellows/runtimes#228 is enacted. After it is released,~~ all
the system parachain collators should be upgraded, and then we can
proceed with phase 3, which will enable async backing in the runtimes.

UPDATE: Indeed, we don't need to wait for the runtime upgrade enactions.
The lookahead collator handles the transition by itself, so we can
upgrade ASAP.

## Scope of changes

Here, we eliminate the dichotomy of having "generic Aura collators" for
the production system parachains and "lookahead Aura collators" for the
testnet system parachains. Now, all the collators are started as
lookahead ones, preserving the logic of transferring from the shell node
to Aura-enabled collators for the asset hubs. So, indeed, it simplifies
the parachain service logic, which cannot but rejoice.

Closes #4041

(cherry picked from commit bda4e75a

* Upgrade `trie-db` from `0.28.0` to `0.29.0` (#3982)

- What does this PR do?
1. Upgrades `trie-db`'s version to the latest release. This release
includes, among others, an implementation of `DoubleEndedIterator` for
the `TrieDB` struct, allowing to iterate both backwards and forwards
within the leaves of a trie.
2. Upgrades `trie-bench` to `0.39.0` for compatibility.
3. Upgrades `criterion` to `0.5.1` for compatibility.
- Why are these changes needed?
Besides keeping up with the upgrade of `trie-db`, this specifically adds
the functionality of iterating back on the leafs of a trie, with
`sp-trie`. In a project we're currently working on, this comes very
handy to verify a Merkle proof that is the response to a challenge. The
challenge is a random hash that (most likely) will not be an existing
leaf in the trie. So the challenged user, has to provide a Merkle proof
of the previous and next existing leafs in the trie, that surround the
random challenged hash.

Without having DoubleEnded iterators, we're forced to iterate until we
find the first existing leaf, like so:
```rust
        // ************* VERIFIER (RUNTIME) *************
        // Verify proof. This generates a partial trie based on the proof and
        // checks that the root hash matches the `expected_root`.
        let (memdb, root) = proof.to_memory_db(Some(&root)).unwrap();
        let trie = TrieDBBuilder::<LayoutV1<RefHasher>>::new(&memdb, &root).build();

        // Print all leaf node keys and values.
        println!("\nPrinting leaf nodes of partial tree...");
        for key in trie.key_iter().unwrap() {
            if key.is_ok() {
                println!("Leaf node key: {:?}", key.clone().unwrap());

                let val = trie.get(&key.unwrap());

                if val.is_ok() {
                    println!("Leaf node value: {:?}", val.unwrap());
                } else {
                    println!("Leaf node value: None");
                }
            }
        }

        println!("RECONSTRUCTED TRIE {:#?}", trie);

        // Create an iterator over the leaf nodes.
        let mut iter = trie.iter().unwrap();

        // First element with a value should be the previous existing leaf to the challenged hash.
        let mut prev_key = None;
        for element in &mut iter {
            if element.is_ok() {
                let (key, _) = element.unwrap();
                prev_key = Some(key);
                break;
            }
        }
        assert!(prev_key.is_some());

        // Since hashes are `Vec<u8>` ordered in big-endian, we can compare them directly.
        assert!(prev_key.unwrap() <= challenge_hash.to_vec());

        // The next element should exist (meaning there is no other existing leaf between the
        // previous and next leaf) and it should be greater than the challenged hash.
        let next_key = iter.next().unwrap().unwrap().0;
        assert!(next_key >= challenge_hash.to_vec());
```

With DoubleEnded iterators, we can avoid that, like this:
```rust
        // ************* VERIFIER (RUNTIME) *************
        // Verify proof. This generates a partial trie based on the proof and
        // checks that the root hash matches the `expected_root`.
        let (memdb, root) = proof.to_memory_db(Some(&root)).unwrap();
        let trie = TrieDBBuilder::<LayoutV1<RefHasher>>::new(&memdb, &root).build();

        // Print all leaf node keys and values.
        println!("\nPrinting leaf nodes of partial tree...");
        for key in trie.key_iter().unwrap() {
            if key.is_ok() {
                println!("Leaf node key: {:?}", key.clone().unwrap());

                let val = trie.get(&key.unwrap());

                if val.is_ok() {
                    println!("Leaf node value: {:?}", val.unwrap());
                } else {
                    println!("Leaf node value: None");
                }
            }
        }

        // println!("RECONSTRUCTED TRIE {:#?}", trie);
        println!("\nChallenged key: {:?}", challenge_hash);

        // Create an iterator over the leaf nodes.
        let mut double_ended_iter = trie.into_double_ended_iter().unwrap();

        // First element with a value should be the previous existing leaf to the challenged hash.
        double_ended_iter.seek(&challenge_hash.to_vec()).unwrap();
        let next_key = double_ended_iter.next_back().unwrap().unwrap().0;
        let prev_key = double_ended_iter.next_back().unwrap().unwrap().0;

        // Since hashes are `Vec<u8>` ordered in big-endian, we can compare them directly.
        println!("Prev key: {:?}", prev_key);
        assert!(prev_key <= challenge_hash.to_vec());

        println!("Next key: {:?}", next_key);
        assert!(next_key >= challenge_hash.to_vec());
```
- How were these changes implemented and what do they affect?
All that is needed for this functionality to be exposed is changing the
version number of `trie-db` in all the `Cargo.toml`s applicable, and
re-exporting some additional structs from `trie-db` in `sp-trie`.
