This removes the unused field trials `WebRTC-SimulcastScreenshareUpswitchHysteresisPercent` and `WebRTC-SimulcastScreenshareUpswitchHysteresisPercent` as well as the `video_hysteresis` and `screenshare_hysteresis` parameters in `WebRTC-VideoRateControl`. The hysteresis parameters in `WebRTC-StableTargetRate` are currently left, their future is unclear...
