Generalize onion message ForwardTlvs::next_node_id

Allow either using a node id or a short channel id when forwarding an
onion message. This allows for a more compact representation of blinded
paths, which is advantageous for reducing offer QR code size.

Follow-up commits will implement handling the short channel id case as
it requires looking up the destination node id.
