Åsa Persson 0122e8443b Reland "Remove sent framerate and bitrate calculations from MediaOptimization."
TBR=sprang@webrtc.org

This is a reland of af721b72cc
Original change's description:
> Remove sent framerate and bitrate calculations from MediaOptimization.
> 
> Add RateTracker for sent framerate and bitrate in SendStatisticsProxy.
> 
> Store sent frame info in map to solve potential issue where sent framerate statistics could be
> incorrect.
> 
> Bug: webrtc:8375
