[event] record state access events

[kjcamann]

There are a few changes here:

• The ExecuteTransaction and ExecuteSystemTransaction functors are given a State object rather than creating one, so it can be owned by the outer transaction fiber. After the functor is done executing the transaction, this outer fiber gives the State to the recording code

• class State gains the State::clear method, so that it can be reset when re-execution is needed

• record_txn_events.cpp gains functions for recording State objects as ACCOUNT_ACCESS_LIST_HEADER, ACCOUNT_ACCESS, and STORAGE_ACCESS events

• All state-affecting changes to the block that occur before transaction and after the transaction are also recorded

Pull Request Overview

This PR refactors transaction execution to enable recording of state access events. The key change is moving State object ownership from within transaction execution functors to the outer transaction fiber, allowing state information to be captured after execution completes.

Key changes:

• ExecuteTransaction and ExecuteSystemTransaction functors now accept a State& parameter in their operator() instead of creating State internally
• Added State::clear() method to enable state reuse during transaction retries
• Implemented state access event recording via new ACCOUNT_ACCESS_LIST_HEADER, ACCOUNT_ACCESS, and STORAGE_ACCESS events
