Backport #5712 into `stable2409` from franciscoaguirre.

Now the XCM emulator has a log every time `execute_with` is called, to know
which chain is being used.
Also, the logs for UMP, DMP, HRMP processing were included in the `xcm` log filter
and changed from showing the message as an array of bytes to a hex string.
This means running the tests with `RUST_LOG=xcm` should give you everything you
need, you can always filter by `RUST_LOG=xcm::hrmp` or any other if you need it.

As requested here:
https://github.com/paritytech/polkadot-sdk/pull/5688#issuecomment-2352939516

I don't think it need to be backported to 2407, as the issue was not
present there yet.

This backports https://github.com/paritytech/polkadot-sdk/pull/5127, to
the stable branch.

Unfortunately https://polkadot.subsquare.io/referenda/1051 passed after
the cut-off deadline and I missed the window of getting this PR merged.

The change itself is super low-risk it just prints a new message to
validators that starting with January 2025 the required minimum of
hardware cores will be 8, I see value in getting this in front of the
validators as soon as possible.

Since we did not release things yet and it does not invalidate any QA we
already did, it should be painless to include it in the current release.

(cherry picked from commit a947cb83)

Backport #5581 into `stable2409` (cc @franciscoaguirre

).

The dry-run shows in `forwarded_xcms` all the messages in the queues
at the time of calling the API.
Each time the API is called, the result could be different.
You could get messages even if you dry-run something that doesn't send
a message, like a `System::remark`.

This commit fixes this by clearing the message queues before doing the
dry-run, so the only messages left are the ones the users of the API actually
care about.

This backports original PR:
https://github.com/paritytech/polkadot-sdk/pull/5527 to the release
branch


```

The https://github.com/paritytech/polkadot-sdk/issues/5512 has surfaced that we reported a `BestBlock` event for a block not previously reported via `NewBlock`.

This is because of a race between:
- the stream of events that announces new blocks
- `self.client.info().best_block`

It is possible that `client.info()` contains newer information than the information polled from the block stream (that may be lagging).

To mitigate this, instead of relying on the client's info use the last finalized block to emit a new event.

There are two cases when a new best block event is emitted:
- The best block is in the pruned list and is reported immediately
- The best block is not a descendant of the last finalized block 

Closes: https://github.com/paritytech/polkadot-sdk/issues/5512 

Thanks @jsdw and @josepot for helping debug this

Allow free Snowbridge consensus updates, if the header interval is
larger than the configured value (set to 32, so once a epoch).

This PR also moves the Rococo Snowbridge pallet config into its own
module.

Original PR: https://github.com/Snowfork/polkadot-sdk/pull/159

----------

Original `pr_5201.prdoc` is present but moved to release dir, ergo
`R0-Silent` for this backport PR.
