Add floating point volume handling to AudioMixer
Use floating point volume in AudioMixer mixing when floating
point input is used with the new mixer engine.
AudioResampler is updated to take floating point volume to match.
Both legacy integer and floating point mixer engines work.
For now, integer volume is used when the new mixer engine
runs in integer input mode, for backward compatibility with
the legacy mixer. The new mixer engine will generally run in
floating point input mode. When the legacy path is removed,
the integer volumes will be removed.

Replace int bitDepth with audio_format_t in Resampler
Remove mBitDepth from class (not used).
Replace with audio_format_t in factory method to distinguish
between float and pcm 16-bit.

Improve dynamic audio resampler filter generation
Improve dynamic audio resampler filter generation speed by 2x.
The resulting filters should be the same (excepting roundoff).
Also added check for upsampling sample rate changes to share
previously generated filters.
Modify the profiling to improve output format and sampling result
reliability.
