Revert of Reland  588523002: Fix the way how we create webrtc::AudioProcessing in Chrome (patchset #5 id:80001 of https://codereview.chromium.org/597923002/)

Reason for revert:
It fails some aec dump content browser tests on windows, and likely it also breaks the aec dump production code, it is safer to revert it since cut happens today.
