This feature allows the RCP to support multiple host stacks on different PANs by making use of the spinel Interface ID. Created unit tests for testing multipan feature with multiple ot-instance support. Based on Si-Labs PR #8914 by @parag-silabs, but a little different approach. Instead of handling everything by a single sub-mac instance, multiple OpenThread instances are created on RCP side that map to different IID. Thanks to this there are separate data kept for each interface. Platform is able to determine interface by ot instance pointer passed as an argument to most of the API functions. Tx/scan queue was removed as it is possible to request transmission in parallel, it is up to the platform to decide if it should fail or queue second tx or it has two radios available. NOTE: Platform needs to provide different otRadioFrame of each instance and the processing needs to take into account the instance being used.
