Benjamin Otte 7b76170f46 gpu: Flip the big switch
Rewrite all shaders to use 2 predefined samplers called GSK_TEXTURE0 and
GSK_TEXTURE1 instead of wrapper functions.

On GL and Vulkan compat mode, these map directly to samplers.
On Vulkan proper, they map to 2 indices into the texture array, like
before.

From now on, the old nvidia GPUs - ie the 3xx drivers - should start
working again.
