This CL refactors AGC2 and fixes the order with which the fixed and the adaptive digital gain controllers are applied - i.e., fixed first, then adaptive and finally limiter. FixedGainController has been removed since we need to split the processing done by the gain applier and the limiter. Also, GainApplier and Limiter are easy enough to be used without a wrapper and a wrapper would need 2 separated calls in the right order - i.e., error prone. FrameCombiner in audio mixer has been adapted and now only uses the limiter (which is what is needed since no gain is applied). The unit tests for FixedGainController have been moved to gain_controller2_unittests. They have been re-adapted and ChangeFixedGainShouldBeFastAndTimeInvariant has been re-tuned.
