all: implement eip-7702 set code tx (ethereum#30078)

This PR implements EIP-7702: "Set EOA account code". 
Specification: https://eips.ethereum.org/EIPS/eip-7702

> Add a new transaction type that adds a list of `[chain_id, address,
nonce, y_parity, r, s]` authorization tuples. For each tuple, write a
delegation designator `(0xef0100 ++ address)` to the signing account’s
code. All code reading operations must load the code pointed to by the
designator.
