feat(consensus): bincode compatibility for header and transaction types

[shekhirin]

Closes #1349

Introduces the serde-bincode-compat feature that provides bincode-compatible implementations of serde serialization/deserialization to use with serde_as macro.

Example usage

alloy/crates/consensus/src/header.rs

Lines 835 to 846 in af593d2

	/// ```rust
	/// use alloy_consensus::{serde_bincode_compat, Header};
	/// use serde::{Deserialize, Serialize};
	/// use serde_with::serde_as;
	///
	/// #[serde_as]
	/// #[derive(Debug, PartialEq, Eq, Serialize, Deserialize)]
	/// struct Data {
	/// #[serde_as(as = "serde_bincode_compat::Header")]
	/// header: Header,
	/// }
	/// ```

open to renaming this feature to something more generic than bincode, because it also unlocks messagepack via https://github.com/3Hren/msgpack-rust

why is this required for all the tx types?

why is this required for all the tx types?

they have a skip_serializing_if attribute, and we use tx types in the block body in Reth
