Implement pallet-asset-rewards

[liamaharon]

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

• Emulation tests
• Fill in Freeze logic (blocked [Assets] Implement fungibles::freeze::Mutate #3342) and re-run benchmarks

Looks good to me, some minor comments, one major one: should we implement a way to cleanup a pool, get deposit back, remove all related items? #3926 (comment)
