eip4844: use alloy TxEip4844

@tcoratger mind pointing out where exactly do we need encode_fields in reth? it is pretty much internal alloy utility function, so making it pub would likely mean we just need additional specialized fn

[klkvr]

If it's here

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

Lines 130 to 140 in 71e0178

	let blob_tx_header = Header { list: true, payload_length };
	// Encode the blob tx header first
	blob_tx_header.encode(out);
	// Encode the inner tx list header, then its fields
	tx_header.encode(out);
	self.transaction.encode_fields(out);
	// Encode the signature
	self.signature.encode(out);

then I think this is just self.transaction.encode_with_signature_fields(self.signature, out)?

@klkvr nice just fixed

lgtm, pending conflicts caused by #10262

tested on a local db and decoded existing txes fine 👍
