This maps, in both directions, [Audio/Video]TrackInterface with [Voice/Video][Sender/Receiver]Info. This mapping is necessary for RTCStatsCollector to know the relationship between RTCMediaStreamTrackStats and RTC[In/Out]boundRTPStreamStats, and to be able to collect several RTCMediaStreamTrackStats stats.
