dev: impl get_state_updates using re_execute_transactions

[tdelabro]

What is the problem?

State updates used to be stored directly onto the disk for each block.
They are not anymore since #1580, meaning the RPC won't work anymore.

What to do?

Replace the current implementation with a call to re_execute_transactions adding the option to have the StateDiff.
Execute all the tx on the same CachedState, and at the end, return the StateDiff

Remove state_diff and get_state_diff and cairo_job and update_cairo_job from crates/client/db/src/da_db.rs. I think we should keep the last_proved_block logic for now.
