Activate the pre-amplifier in AudioProcessing.

Browse Source 
It's a module for applying a gain to the capture signal.
The gain is the first processing step in APM.

After this CL, these two features work:
* The PreAmplifier can be activated with
  AudioProcessing::Config::pre_amplifier
* The PreApmlifier can be controlled after APM creation by
  AudioProcessing::SetRuntimeSetting.

What's left is a change to AecDumps and to AecDump-replay.

NOTRY=True # 1-line change, tests just passed.
