Add information about microphone gain changes to AEC3

Add information about microphone gain changes to AEC3

Changes in the microphone gain are effecting the AEC in the sense
that each change in the microphone gain is a change in the echo 
path seen by the AEC. This CL utilizes the ability of AEC3 to 
leverage information about known changes in the analog microphone
gain.

Hi,
This is a very short CL that hooks up the analog AGC functionality with AEC3. 

It would be great if you could take a look at it!
