Reviewed by Eric Carlson.

Add support for setting the VideoFrame presentationTime based on the WebCodecsVideoFrame timestamp.
In the future, the WebCodecsVideoFrame timestamp will be removed in favour of the VideoFrame presentationTime.

Make sure to have MediaStreamTrackProcessor correctly create the WebCodecsVideoFrame with the presentationTime.
