vulkan: Add nonuniformEXT() where needed

Browse Source 
The magical term to know about (because the GLSL compiler or the
validation layers sure as hell don't) is:

  "dynamically uniform expression"

because if you don't have that when indexing a texture or buffer array,
you need to add nonuniformEXT() around the index variable.

Fixes the close icon on AMD having glitches of the previous icon visible
in some pixels.
