nir: Add a pass to lower TES patch_vertices intrinsics to a constant.

In Vulkan, we always have both the TCS and TES available in the same
pipeline, so we can simply use the TCS OutputVertices execution mode
value as the TES PatchVertices built-in.

For GLSL, we handle this in the linker.  But we could use this pass
in the case when both TCS and TES are linked together, if we wanted.
