[SDL 0150] Enhancing onHMIStatus with a New Parameter for Video Streaming State

Proposal: Enhancing onHMIStatus with a New Parameter for Video Streaming State

This proposal adds a new parameter videoStreamingState to onHMIStatus notification so that SDL core can notify an app to stop video streaming. This helps SDL Core handle the use cases of the coexistence of a navigation app and a projection app or multiple navigation/projection apps.
