ipc: ipc_service: Rework multi-instance backend. Only one single IPC service backend is currently present: multi_instance backend. This backend is heavily relying on the RPMsg multi_instance code to instanciate and manage instances and endpoints. Samples exist for both in the samples/subsys/ipc/ directory. With this patch we are "unpacking" the RPMsg multi_service code to make it more modular and reusable by different backends. In particular we are re-organizing the code into two helper libraries: an RPMsg library and a VRING / virtqueues static allocation library. At the same time we rewrite the multi_instance backend to make fully use of those new libraries and remove the old multi_instance sample. Signed-off-by: Carlo Caione <ccaione@baylibre.com>

ipc_service: Add new RPMsg with static VRINGs backend Introduce a new RPMsg with static VRINGs backend. This new backend makes easy to generate and use IPC instances backed by OpenAMP using the DT. Each instance is defined in the DT as (for example): ipc: ipc { compatible = "zephyr,ipc-openamp-static-vrings"; shm = <&sram_ipc0>; mboxes = <&mbox 0>, <&mbox 1>; mbox-names = "tx", "rx"; role = "primary"; status = "okay"; }; It is then possible to register an send data through endpoints using the IPC service APIs.
