Unify AGC2 experiment field trials into one

In order to experiment with AGC2 and TS at the same time, 3 field
trials are removed and merged into `WebRTC-Audio-GainController2`,
which is existing.

New parameters for the `WebRTC-Audio-GainController2` field trial:
- `switch_to_agc2`: true by default; when true, the gain control
  switches to AGC2 (both for the input volume and for the adaptive
  digital gain);
- `min_input_volume`: minimum input volume enforced by the input
  volume controller when the applied input volume is not zero;
- `disallow_transient_suppressor_usage`: when true, TS is never
  created.

Removed field trials:
- `WebRTC-Audio-Agc2-MinInputVolume`: now a parameter of
  `WebRTC-Audio-GainController2`;
- `WebRTC-ApmTransientSuppressorKillSwitch`: now a parameter of
  `WebRTC-Audio-GainController2`;
- `WebRTC-Audio-TransientSuppressorVadMode`: automatically inferred
  from `WebRTC-Audio-GainController2`.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
