This PR extends the journal to track the pre-transaction values of
mutated balances, nonces, and code.
At the end of the transaction, these values are used to filter out no-op
changes, such as balance transitions from a-> b->a. These changes are
excluded from the block-level access list.
Additionally, there is a dedicated `bal.ConstructionBlockAccessList`
objects for gathering the state reads and writes within the current
transaction. These state writes will be keyed by the block accessList
index.
