Reland "Add a high bitrate full stack test with fake codec"

In this reland, I disabled high bitrate webrtc perf test on Android32.

This is a reland of 15df2774f4e85cf8900768c1793edcf17d651dcd

Original change's description:
> This CL adds a fake codec factory  in WebRTC that can be used in tests to
> produce target bitrate output.

> We also add a high bitrate test that makes use of fake codec. This test assumes
> ideal network conditions with target bandwidth being available and exercises
> WebRTC calls with a high target bitrate(100 Mbps) end-to-end.
