Move icmsg_buf to lib/os and rename to spsc_pbuf (Single Producer
Single Consumer Packet Buffer). It is a generic module and initially
was created as internal module for ipc service.

Recently OpenAMP introduced the possibility to set the sizes for TX and
RX buffers per created instance. Expose this also to Zephyr users by
using a DT property "zephyr,buffer-size".
For the sake of simplicity use the same DT property to set the buffer
size for both TX and RX buffers.

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

This commit adds ipc backend, that relies on simple
inter core messaging buffer also added by this commit.
This backend is configurable with DT overlay. Each
ipc instance could be defined with ipc-icmsg commpatible.

Extend the RPMsg structs to accommodate for the introduction of new
backends and contextually fix the ipc_rpmsg_static_vrings_mi backend
(the only user).
Rework also some comments and ipc_service glue code.

The IPC libraries will be used by several backends. Move the libraries
out in a new 'lib' directory.
