980c4601e1 AGC2: retuning and large refactoring 
- Bug fix: the desired initial gain quickly dropped to 0 dB hence
  starting a call with a too low level
- New tuning to make AGC2 more robust to VAD mistakes
- Smarter max gain increase speed: to deal with an increased threshold
  of adjacent speech frames, the gain applier temporarily allows a
  faster gain increase to deal with a longer time spent waiting for
  enough speech frames in a row to be observed
- Saturation protector isolated from `AdaptiveModeLevelEstimator` to
  simplify the unit tests for the latter (non bit-exact change)
- AGC2 adaptive digital config: unnecessary params deprecated
- Code readability improvements
- Data dumps clean-up and better naming

087e9bed41 AGC2 Limiter class renamed. 
Limiter has been renamed to LimiterDbGainCurve, which is a more correct name
and will allow in a follow-up CL to reuse the Limiter name for GainCurveApplier.
This is done to allow to use the limiter without instancing the fixed digital
gain controller and then to fix an AGC2 issue (namely, fixed gain applied after
the adaptive one).

03ad9b892c Fine-grained limiter metrics. 
The FixedGainController is used in two places.
One is the AudioMixer. There it's used to limit the audio level after
adding streams. The other is GainController2, where it's placed after
steps that could boost the audio level outside the allowed range.

We log metrics from the FGC. To avoid confusion, this CL makes the two
use cases log to different histograms.

a05ee82c4c Fixed Digital mode of AGC2 implementation finished. 
This CL adds the GainCurveApplier (GCA). It owns a
FixedDigitalLevelEstimator (LE) and an InterpolatedGainCurve
(IGC). The GCA uses the LE to compute the input signal level, looks up
a gain from IGC and applies it on the signal.

The other IGC and LE submodules were added in previous CLs [1] and
[2].

This CL also turns on AGC2 in the APM fuzzer.
