According to the SYCL 2020 specification:
However, the current implementation allows also sycl::item and any argument types convertible from a sycl::item. This commit addresses this discrepancy by disallowing anything other than sycl::nd_item and all types convertible from sycl::nd_item in this kind of parallel_for. Since this may break existing code, this new restriction is guarded by the SYCL2020_CONFORMANT_APIS preprocessor macro.
