Expose RTP timestamp from VideoFrameMetadata to JavaScript

This change makes the RTP timestamp available on the JavaScript facing
VideoFrame.metadata dictionary when it is set in the underlying native
media::VideoFrameMetadata.

This enables applications using MediaStreamTrackProcessor (e.g., to
render frames to a canvas) or WebCodecs (e.g., for decoding and
presentation) to correlate Web exposed frames with transport level
metadata such as RTP timing.
