RTCMediaStreamTrackStats collected on a per-attachment basis.

According to recent spec change:
https://github.com/w3c/webrtc-stats/pull/138/files

This establishes the relationship between tracks and
[Voice/Video][Sender/Receiver]Info(s). Follow-up CLs will easily be able
to collect more stats from them.
