On ARM devices, WebRTC always performs the audio processing at a maximum
of 32 kHz. The reason for this is that previously the 48 kHz splitting
filters used caused issues related to CPU-performance on ARM. This has
now been addressed and this CL activates 48 kHz processing at 32 kHz.

The CL also adds a kill-switch that can be used to turn off this support
for ARM devices, in case it would turn out to be an issue.
