The icmsg backend for ipc_service has a limitation of supporting only
on endpoint. This limitation is acceptable for many IPC instances.
However, some require to use multiple endpoints sharing a single
instance. To preserve the simple and the most efficient single-instance
backend, a separated backend is introduced implementing a wrapper
around icmsg core which adds multiple endpoints support.
There are two multi-endpoint ipc_service icmsg backends: one in the
initiator role, and the other one in the follower role. In a IPC
configuration one end of communication must be in the follower role
while the other one is in the initiator. The initiator initiates
an endpoint discovery handshake to establish enpoint identifiers for
requested endpoint names. The follower responds to requests sent by
the initiator.
