[remoting WebRTC] Add quantizer to per-frame statistics.

This adds the VP8/9 frame quantizer to the stats for each frame.
This will enable the website to show a graph of these values over time.

This also adds new FrameStats unittests, and fixes a capturer_id
initialization bug discovered by the unittest.

Change frame 'quantizer' to 'quality' in video_stats.proto.

In the per-frame statistics, instead of sending raw frame quantizer
values from the VPX encoder (from 0-63), this sends a simple measure of
frame quality, from 0-100, with 100 being a lossless frame.
