feat(primitives): Add y_parity_byte_non_eip155 to Parity

[Evalir]

Motivation

In the case of a signature without EIP155 applied, the y_parity byte should be returned as 27 or 28. y_parity_byte only returns it as {0,1}.

Solution

This adds a fn y_parity_byte_non_eip155 which, when not having an EIP155 parity, we get 27 or 28, or None otherwise.

lgtm, any follow up PR needed here to solve the bug in anvil?

[Evalir]

yep @onbjerg, we'll need to change how the v value is represented on the signature as_bytes impl (namely, use y_parity_byte_non_eip155 and if None, fallback to y_parity_byte), and after, we'll need a minor release of core to bump on alloy-rs/alloy.
