Implemented by short-circuiting calls to RequestVideoData in MDSM so no frames are decoded. Resuming playback when video moves to foreground by using the SeekTask/SeekJob/Seek in MDSM with result of GetMediaTime(). Special consideration is made to only seek the video part of Seek() to remove an audible glitch in the audio playback when the video becomes visible again. MozReview-Commit-ID: 7YFDTanslXu
