[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.

abbdc13e68 [CUDA][SPIRV] Use OpenCLKernel CC for CUDA -> SPIRV
Select the OpenCLKernel calling convention for kernels when compiling
CUDA targeting SPIR-V.

In this way the generated LLVM IR will have a spir_kernel calling
convention that will be translated to an OpEntryPoint when converting
to SPIRV.
