This reverts commit 6a18f06bd0.

Reason for revert: reverted by mistake

Original change's description:
> Revert "APM: rename `AnalogGainStatsReporter` to `InputVolumeStatsReporter`"
>
> This reverts commit b5319fabee.
>
> Reason for revert: audioproc_f crash 
>
> Original change's description:
> > APM: rename `AnalogGainStatsReporter` to `InputVolumeStatsReporter`
> >
> > Adopt the new naming convention, which replaces "analog gain" and
> > "mic level" with "input volume", in the input volume stats reporter.
