Subject: [PATCH] audio: add support for aec recording path

    Add Audio Capture Eraser Enable to switch
    Eraser for recording path.
    For gain of this path, we shouldn't apply
    software gain, because the input source is
    from hotword pipeline.

Test: build pass
Bug: 172266161
Change-Id: Iabe372e7fe91e557ba9125af14bfb61606c09ea0
