Subject: [PATCH] audio: add support for aec recording path [DO NOT MERGE]

    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
