Closes #3149 

## Description

This PR introduces `pallet-asset-rewards`, which allows accounts to be
rewarded for freezing `fungible` tokens. The motivation for creating
this pallet is to allow incentivising LPs.

See the pallet docs for more info about the pallet.

## Runtime changes

The pallet has been added to
- `asset-hub-rococo`
- `asset-hub-westend`

The `NativeAndAssets` `fungibles` Union did not contain `PoolAssets`, so
it has been renamed `NativeAndNonPoolAssets`

A new `fungibles` Union `NativeAndAllAssets` was created to encompass
all assets and the native token.

## TODO
- [x] Emulation tests
- [x] Fill in Freeze logic (blocked
https://github.com/paritytech/polkadot-sdk/issues/3342) and re-run
benchmarks

This PR provides the partial results of the `GetRecord` kademlia query.

This significantly improves the authority discovery records, from ~37
minutes to ~2/3 minutes.
In contrast, libp2p discovers authority records in around ~10 minutes. 

The authority discovery was slow because litep2p provided the records
only after the Kademlia query was completed. A normal Kademlia query
completes in around 40 seconds to a few minutes.
In this PR, partial records are provided as soon as they are discovered
from the network.

### Testing Done

Started a node in Kusama with `--validator` and litep2p backend.
The node discovered 996/1000 authority records in ~ 1 minute 45 seconds.

Closes https://github.com/paritytech/polkadot-sdk/issues/6767.

The return type of the host function `caller_is_root` was denoted as
`u32` in `pallet_revive_uapi`. This PR fixes the return type to `bool`.

As a drive-by, the PR re-exports `pallet_revive::exec::Origin` to extend
what can be tested externally.

This PR rejects inbound requests from banned peers (reputation is below
the banned threshold).

This mirrors the request-response implementation from the libp2p side.
I won't expect this to get triggered too often, but we'll monitor this
metric.

While at it, have registered a new inbound failure metric to have
visibility into this.

Introduce `frame_system::Pallet::run_to_block`,
`frame_system::Pallet::run_to_block_with`, and
`frame_system::RunToBlockHooks` to establish a generic `run_to_block`
mechanism for mock tests, minimizing redundant implementations across
various pallets.

Closes #299.
