Change for 7702 for devnet-4

[ak88]

New spec for 7702 here: https://eips.ethereum.org/EIPS/eip-7702

Changes

• PER_AUTH_BASE_COST now costs 15.000
• Fields are bounded as: assert auth.chain_id < 2 **64 assert auth.nonce < 2 **64 assert len(auth.address) == 20 assert auth.y_parity < 2 **8 assert auth.r < 2 **256 assert auth.s < 2 **256
• A zero address delegation will now reset the account to no code.
• EXTCODEHASH returns 0 on empty accounts as well.

Tuple fields have been bounded by their type during RLP serialization/deserialization, so any field exceeding the bounds will result in RlpException
