I'm not sure how the callback weights are taken into account inside pallet_assets (I couldn't find anything in code), but since we are doing DB writes who will be paying for it?

Pull Request Summary
Adds support for automatic EVM revert code registration for XC20.
Each time a new asset is created, an attempt will be made to insert the revert code.
If it succeeds, smart contracts will be able to immediately access the asset.
In case of failure, whole asset registration process is reverted.
Docs update: AstarNetwork/astar-docs#411
Removed some deprecated & unused code.
