  Log Message:
  [clang][CUDA][Windows] Fix compilation error on Windows with `uint32_t __nvvm_get_smem_pointer`

The change fixes https://github.com/llvm/llvm-project/issues/54609 (the second reported issue) by eliminating a compilation error occurring only on Windows while trying to compile any CUDA source file by clang (-x cuda).

clang -x cuda <any_cu_source>


__clang_cuda_intrinsics.h(517,19): error GC871EEFB: unknown type name 'uint32_t'; did you mean 'cuuint32_t'?
__device__ inline uint32_t __nvvm_get_smem_pointer(void *__ptr) {
C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.6/include\cuda.h:57:26: note: 'cuuint32_t' declared here
typedef unsigned __int32 cuuint32_t;
