should we just use TransactionSignatureIsValid
here, as it it used in authority recover, and if it fails there, the entire tx fails. So maybe we can check all aspects of the signature

Makes sense, but I'm holding off until ethereum/EIPs#8865 is merged.
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
