vulkan: move format enumeration into utils functions

Browse source 
This splots the format enumeration into a helper for dsp and raw pod
creation and a common function for the compute filters.

Counting formats with modifiers will be usefull to announce dsp and
raw formats from the same node.

No functional changes.
