[SYCL-MLIR]: Runtime workaround for paralllel_for

[etiotto]

The following test case (using a SYCL parallel_for) fails to run correctly due to a SYCL RT function (dim_loop_impl) which uses a complex templated implementation which "confuses" cgeist. As a workaround we can use the older SYCL RT implementation which used a regular for loop.

Test case:

void host_parallel_for(std::array<int, N> &A) {
  auto q = queue{};
  device d = q.get_device();
  std::cout << "Using " << d.get_info<info::device::name>() << "\n";
  auto range = sycl::range<1>{N};

  {
    auto buf = buffer<int, 1>{A.data(), range};
    q.submit([&](handler &cgh) {
      auto A = buf.get_access<access::mode::write>(cgh);
      cgh.parallel_for<class kernel_parallel_for>(
          range, [=](sycl::id<1> id) { A[3] = 33; });
    });
  }
}

Note: The original clang-format for the RT file I modifies was incorrect. I did not want to push changes related to code formatting so that is the reason the linting job fails.

All SYCL unit tests pass with this RT change.
