The FrameCombiner sub-module of the AudioMixer uses one of two
limiters. One is an AudioProcessingModule with AGC1 enabled and
configured as a limiter. The other is the limiter part of AGC2. This
change removes the APM-AGC1 limiter. This requires small changes to
FrameCombiner, AudioMixerImpl and tests.
We also stop using the finch experiment flag.
