vulkan: enable selecting a compatible representation of format

Browse Source 
When using **integer** images inside shaders, it turns out
that conversion doesn't automatically happen, but we need to
explicitly use the imageviews to get the image exposed as
a suitable representation for the shader.

Finally enables bitexact image representations.
