Reset level estimator when analog gain changes.

In AgcManagerDirect::UpdateGain(), Agc::GetRmsErrorDb() is
called. Depending on the result of that call, the analog gain may be
changed. After an analog gain change, the Agc should be reset, because
it's memory contains now invalid loudness levels.

The Agc in modules/audio_processing/agc/agc.cc resets itself at every
successful Agc::GetRmsErrorDb call. The AdaptiveModeLevelEstimatorAgc
does not. This change makes sure all Agcs are reset from
AgcManagerDirect.

It will cause some Agcs to be reset twice. This is fine, because
Agc::Reset() is cheap and idempotent.
