[TTVD] Increase priority for video rendering crucial threads

During video playback there are several important threads
doing rather lightweight tasks needed to keep rendering
smooth. Stalling any of it might dramatically reduce
user experience. When video playback is on, priority
of Media and VideoFrameCompsitor is increased.
