haydn: Add support for PCMFloat, PCM32 and PCM8 conversions (#4100)

* haydn: Add support for PCMFloat, PCM32 and PCM8 conversions

This adds support in the compatibility layer for other sample format
than PCM16.

This should help extends compatibility with soundio on devices that
doesn't expose PCM16.

I ommited PCM24 conversion for now as it's not simplest of all.

* Address TSRBerry's comment

* Address comments

* Fix conversion issue and clean up saturation usage

* Revert saturation changes

* Address gdkchan's comment
