vulkan: Add pixel-formats to query format properties

Browse source 
We need a database of pixel format properties to remove hardcoded magic
numbers. This commit creates a simple function to query the bytes per
pixel for common RGBA formats.

This should be promoted to or superseeded by a common spa namespaced
version.
