`PyObject_HEAD` is defined (by defaut) as:

  Py_ssize_t ob_refcnt;
  PyTypeObject *ob_type;

so declaring it as a statement macro should allow clang-format to process it correctly. (though this is a variable-like macro, so I need to check if this case is supported)

`PyObject_HEAD_INIT` ends with a comma, which is not supported yet. We would need to add another kind of macro to support that case.
