  [mlir][spirv] Respect client API requirements for 64-bit index

Vulkan requires GPU processor ID/count builtin variables to be
32-bit scalar or vector for all the cases. Similarly there
are special requirements for OpenCL. We need to make sure those
rules are respected when converting using 64bit for index.
