AGC2 config: allow tuning of headroom, max gain and initial gain

Browse Source 
This CL does *not* change the behavior of the AGC2 adaptive digital
controller - bitexactness verified with audioproc_f on a collection of
AEC dumps and Wav files (42 recordings in total).

Tested: compiled Chrome with this patch and made an appr.tc test call
