  [CUDA][SPIRV] Assign global address space to CUDA kernel arguments

(resubmit https://reviews.llvm.org/D119207 after fixing the test for
some build settings)

This patch converts CUDA pointer kernel arguments with default address
space to CrossWorkGroup address space (__global in OpenCL). This is
because Generic or Function (OpenCL's private) is not supported as
storage class for kernel pointer types.
