d5cb477576 AEC3: Audibility improvements 
This CL is created from a work initiated at https://webrtc-review.googlesource.com/c/src/+/61160

The purpose of this work is to improve the performance of the echo canceler (AEC3) when the farend signal contains stationary noises:
- An stationarity estimator of the farend signal has been added for detecting the portions of the farend signal that are pure noise.
- When the echo canceler deals with a portion of the signal that contains basically noise, the echo suppressor is able to back-off and avoid the fading of the nearend speech.
