[v5,0/8] rpmsg: Make RPMSG name service modular

Message

This revision addresses comments received from the previous revision,
i.e V4.  Please see details below.

It starts by making the RPMSG protocol transport agnostic by
moving the headers it uses to generic types and using those in the
current implementation.  From there it re-uses the work that Arnaud
published[1] to make the name service modular.

Tested on stm32mp157 with the RPMSG client sample application.  Applies
cleanly on v5.10-rc2.

Thanks,
Mathieu
