coresight: configuration: Update API to permit dynamic load/unload
Expand the configuration API to allow dynamic runtime load and unload of configurations and features. On load, configurations and features are tagged with a "load owner" that is used to determine sets that were loaded together in a given API call. To unload the API uses the load owner to unload all elements previously loaded by that owner. The API also records the order in which different owners loaded their elements into the system. Later loading configurations can use previously loaded features, creating load dependencies. Therefore unload is enforced strictly in the reverse order to load. A load owner will be an additional loadable module, or a configuration loaded via configfs.
