Revert "Vulkan: Use VK_NV_glsl extension where available, and skip glslang"

This reverts commit d23fd17e1a2c7c617731d619020af021a7658e93.

Dynamic sampler indexing is broken in VK_NV_glsl as of 385.41. The
performance gap doesn't seem to be as wide with the updated driver, so
to save maintaining two code paths, it's easier to just drop the
extension support completely.
