ICameraService: Add methods to query concurrent streaming camera support.

- getConcurrentStreamingCameraIds() :
        returns a list of combinations of camera ids that may stream
        concurrently.

- isConcurrentSessionConfigurationSupported() :
        queries whether camera devices can support the
        corresponding given session configurations concurrently.
