Tommi 06af5b5c64 More use of DeinterleavedView and MonoView in audio classes
Adopt DeinterleavedView and MonoView in the following classes
and deprecate existing versions where external dependencies exist:

* GainApplier
* AdaptiveDigitalGainController
* NoiseLevelEstimator
* VoiceActivityDetectorWrapper (including MonoVad)
