Per spec, in the conformance test urContextCreateWithNativeHandleTest.Success, when calling urContextCreateWithNativeHandle(h_native_handle_t, numDevices, ur_device_handle_t, ur_context_native_properties_t, ur_context_handle_t), if ur_device_handle_t is nullptr then UR_RESULT_ERROR_INVALID_NULL_POINTER will be returned, yet in the test we still expect SUCCESS.
