Subject: [PATCH] fix(chain): Fake FinalizeBlock in PrepareProposal (#1272)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

Refactor:
- Removed the "statedb" field from the "blockchain" struct in
`eth/core/chain.go`, indicating a refactoring of state management
functionality.
- Updated `eth/core/chain_writer.go` to create a new `state.StateDB`
object within `WriteGenesisBlock` and `InsertBlockAndSetHead` functions,
enhancing the modularity of state management.
- Modified `WriteBlockAndSetHead` and `writeBlockWithState` functions to
accept a `state.StateDB` parameter, improving the flexibility of state
changes commitment.

These changes streamline the state management process, potentially
improving the performance and maintainability of the code.
