I'm planning to simplify the validity checks for 7702 in this PR, so I don't think it's necessary to make this change. |

Check (in the txpool and in the main code) that an EIP-7702 transaction is [valid](https://eips.ethereum.org/EIPS/eip-7702#set-code-transaction), namely that: - `to != nil` - `len(authorization_list) != 0` - `authorization.chain_id` is `uint256` - `authorization.nonce` is `uint64` - `authorization.address` is `bytes20` - `authorization.y_parity == 0 || authorization.y_parity == 1` - `authorization.r` is `uint256` - `authorization.s` is `uint256` and `authorization.s <= secp256k1n/2` This PR doesn't implement ethereum/EIPs#8865 or ethereum/EIPs#8845

Currently EIP-7702 mentions that the validity of
sis based on EIP-2 (s <= secp256k1n/2), but EIP-2 itself is a tweak of the pre-Homestead validity check (0 < r < secp256k1n,0 < s < secp256k1n). See ValidateSignatureValues in geth.
