AEC3: Corrected the filter adjustment during analog gain changes

This CL corrects the way that the echo subtractor output is
adjusted during the adjustment of the adaptive filter when the
analog AGC gain changes.

The CL also ensures that the main adaptive filter is not updated
when this occurs.

We would like to merge this issue into M69, as two other issues (listed below) for which we have asked for merge requests rely on this issue.

It has been tested in Chrome Canary and both the manual testing results and the metrics look good.
The merge is considered to be very safe, as the feature is only active beneath an experiment flag, and also has a specific kill-switch.

The CL that would be part of the merge is
-https://webrtc-review.googlesource.com/90401

The two other issues that are dependent on this merge are
-https://bugs.chromium.org/p/chromium/issues/detail?id=867873
-https://bugs.chromium.org/p/chromium/issues/detail?id=869329
and we have also asked for merges of those.

This bug requires manual review: DEPS changes referenced in bugdroid comments.
Please contact the milestone owner if you have questions.
Owners: amineer@(Android), kariahda@(iOS), cindyb@(ChromeOS), govind@(Desktop)
