use alloy Signature type

[klkvr]

Describe the feature

with alloy-rs/core#719 we can now use Signature to store arbitrary signatures.

first step might be to replace SignatureWithParity:

reth/crates/primitives/src/transaction/signature.rs

Line 231 in 3ec5d37

pub(crate) struct SignatureWithParity {

and after that Signature:

reth/crates/primitives/src/transaction/signature.rs

Line 30 in 3ec5d37

pub struct Signature {

we'll need to make sure to correctly implement decoding. right now for legacy transactions we expect v to be 27 or 28, however alloy's signature will succesfully decode any of 0, 1, 27 or 28 which is incorrect rlp
