Rename FloatResamplingAudioProcessor to ToFloatPcmAudioProcessor.

Browse Source 
Resampling as a term is overloaded, however it was raised as a
confusing term in a meeting recently, as the 1P team initially thought
this would change the sample rate. The naming of this `AudioProcessor`
now matches `ToInt16PcmAudioProcessor`.
