[Fix] code hash do not use rlc in 'poseidon-codehash' feature

[noel2004]

The 'poseidon-codehash' feature is specified for our l2geth, in which 'dual codehash' has applied so the codehash field in account can be always contained in a single scalar of the field (even the code hash for empty code). It would be waste of cost if we still apply it as a rlc of the bytes of codehash.

This PR switch each place refering codehash and assign the codehash as single scalar when 'poseidon-codehash' feature is enabled. Execpt for bytecode circuit, only unified change is required for most places in the code (replacing the calling of word_rlc to a specified code_hash function)

Following test should be passed:

• The failed bytecode_invalid_hash_data test before
• Regression for all the unit tests
• A mock proving of the supercircuit on real-world trace from alpha testnet
