Now everything is ready. We can make NotifyQueuedTrackChanges only triggered by TRACK_EVENT_CREATED and TRACK_EVENT_ENDED without breaking anything. Also we make TrackUnionStream no longer copying data in video case.

Replace |MediaPipelineTransmit::PipelineListener::NotifyQueuedTrackChanges| with |MediaPipelineTransmit::PipelineVideoSink::SetCurrentFrames|. We only need to deal with the video case since audio will be routed to |NotifyQueuedAudioData|.

Add MediaStreamVideoRecorderSink into MediaEncorder. In this patch, I still keep use duration to pass to TrackEncoders. Don't want to make this bug too big and out of control. We can file a new bug to change TrackEncoders use TimeStamp only.

Make CaptureTask to inherite from MediaStreamVideoSink. The main change is to move the logic of |NotifyQueuedTrackChanges| to |SetCurrentFrames|.
The original image capture is not modified for support multiple video MediaStreamTracks. The design still used the track id in owned media stream. The should be fixed in the following bug if we still want to support ImageCapture in multiple video tracks case.

In this patch, we first deal with the case of MediaElement. Now we replace |PlayVideo| with |VideoFrameContainer::SetCurrentFrames| in |SourceMediaStream::AppendToTrack|. The MSG use TimeStamp::Now() for the TimeStamp of each video frame in most of case except MediaElement case. Becasue the MediaElement has its own VideoQueue, we need to calucalte the correct Timestamp based on the StartTimeStamp of this MediaStream and the elpased time of the video frame in DecodedStream.

MediaStreamVideoSink is the base class of VideoFrameContainer, CaptureTask(ImageCapture), MediaStreamVideoRecorderSink(MediaRecoreder) and PipelineVideoSink(WebRTC-MediaPipelineTransmit). In this patch, I change VideoFrameContainer only. The rest of cases will be changed in latter patches of this bug.
