Description

https://wicg.github.io/video-rvfc/#dictdef-videoframecallbackmetadata defines some metadata that might be useful to be in VideoFrameMetadata.
It might also be useful to expose future VideoFrameMetadata fields in VideoFrameCallbackMetadata.
The following could be done:

  1. VideoFrameCallbackMetadata derives from VideoFrameMetadata
  2. Move some metadata from VideoFrameCallbackMetadata to VideoFrameMetadata: captureTime, receiveTime and rtpTimestamp.

@tguilbert-google, @dalecurtis, thoughts?
