Reland "Add ability to state whether the APM output will be used"

Browse Source 
This is a reland of 8be2f201ba8790501f6f3fa39f00017f02fca46d

Original change's description:
> Add ability to state whether the APM output will be used
> 
> This CL adds the ability for the surrounding code to state that the
> APM output will not be used. The intended usecase for this is to allow
> APM to run at a lower complexity when the endpoint is muted.
> When APM has been informed that the output will not be used, it can
> turn off code that is needed only for ensuring that the output audio
> will sound good.
>
