core,API: Add bridge support
This change introduces a facility to bridge messages between two
bindings.
This is implemented through a new mctp_bridge_busses() API, which
applies a new routing policy, sending packets from one binding to the
other. This is in contrast to the current policy of dropping all
non-local packets.
To do this, the message context code needs to know both source and
destination EIDs, so add them to the mctp_msg_ctx_lookup() criteria.
Also, add a small test for bridge mode.
