greybus: connection: add per-connection request handlers
Add a connection request-handler field to struct gb_connection that is
set when the connection is enabled.
This is a step towards removing the legacy protocol abstraction from
core, and will also be used to implement unidirectional connection
states (e.g. only outgoing operations are allowed).
