chore: fix mpt sync

[greged93]

The code_size is used in extcodesize, and removing it from the Account lead to a default value value of 0 to be used for the field when retrieving an account from database and converting it to an revm::primitives::AccountInfo. This further lead to a sync error (gas used mismatch) at block 3404 because an incorrect code size of 0 was used.

In order to reenable syncing in the MPT mode without adding too much diff with upstream, we remove the code_size "shortcut" that is taken in the Scroll revm fork for the extcodesize, and instead retrieve the code from database and return its length as done in the latest commit on the scroll-evm-executor/reth/v51 branch.

Resolves #130

I think this is the correct approach. CI seems to be failing, did you forget to add the updated workspace Cargo.toml file?
