Add shader non-uniform indexing support (#91)

This PR marks ALL texture indexes as nonuniform to fix an issue with the paths in Tomodachi Life: Living the Dream on AMD cards. It should have a negligible impact on performance (and it should not have an impact at all on NVIDIA cards!)

It's caused by what is called 'implicit non-uniform sampler array indexing'. The idea is basically that some GPUs optimize texture lookups from indexed texture arrays, by assuming that you are never going to index different textures within a single workgroup. What this causes is that visual glitch where a subgroup is tasked with rendering a block of the screen, and in the boundaries some cores are indexing the wrong texture.
