Not implemented static constexpr dimensions member of few range/id-like types

[aleksmesh]

Not implemented static constexpr dimensions member of next range/id-like types:

• sycl::id
• sycl::range
• sycl::nd_range
• sycl::h_item
• sycl::item
• sycl::nd_item

To Reproduce

#include <stdlib.h>

#include <iostream>

#include <sycl.hpp>

int main() {
  std::cout << "sycl::id<1>::dimensions = " << sycl::id<1>::dimensions << std::endl;
  std::cout << "sycl::range<1>::dimensions = " << sycl::range<1>::dimensions << std::endl;
  std::cout << "sycl::nd_range<1>::dimensions = " << sycl::nd_range<1>::dimensions << std::endl;
  std::cout << "sycl::item<1>::dimensions = " << sycl::item<1>::dimensions << std::endl;
  std::cout << "sycl::h_item<1>::dimensions = " << sycl::h_item<1>::dimensions << std::endl;
  std::cout << "sycl::nd_item<1>::dimensions = " << sycl::nd_item<1>::dimensions << std::endl;
  return EXIT_SUCCESS;
}

To build
clang++ -fsycl sample_dimensions_member.cpp -o sample
