Implement:

• evm_snapshot: Takes a snapshot of the current state of the EVM (blockchain state, contracts, balances, etc.) at a given point in time and returns a snapshot id.
• evm_revert: Reverts the EVM's state to a previously taken snapshot, undoing all state changes made after that point.
• anvil_rollback: Revert the state to a previous block height.

What's important is that once we revert the blockchain, we no longer can undo the revert (we cannot go back to the future), which is a key simplification.

Let's try using substrate chain reversion: https://paritytech.github.io/polkadot-sdk/master/sc_client_api/backend/trait.Backend.html#tymethod.revert
