feat: Add 7702 tx enum

[moricho]

Motivation

The 7702 tx type has been added at #1046, so it would be better to support 7702 tx enum in the consensus layer as well.

Solution

Adds a new variant Eip7702 to the TypedTransaction enum in consensus.

pub enum TypedTransaction {
  ...
  /// EIP-7702 transaction
  #[cfg_attr(feature = "serde", serde(rename = "0x04", alias = "0x4"))]
  Eip7702(TxEip7702),
}

According to the above change, also adds authorization_list field to the TransactionRequest and its accessor to the TransactionBuilder

thanks for this!

this type is will be supported by devnet1 soon, but I think we can actually include it already, though we should wait until devnet is up

@mattsse thanks, it’s fine to leave this until devnet is ready :)
