Rework radio support for new gRPC API

Update the stubbed out radio support library to use the new gRPC API.
The "Radio" Qt wrapper object has been renamed to "RadioClient" to
avoid conflicting with the generated gRPC API code.  This somewhat
aligns with the naming that has been used with the AppLauncher
support.
