bpo-40170: PyObject_GET_WEAKREFS_LISTPTR() becomes a function (GH-19377)
Convert the PyObject_GET_WEAKREFS_LISTPTR() macro to a function to hide implementation details: the macro accessed directly to the PyTypeObject.tp_weaklistoffset member. Add _PyObject_GET_WEAKREFS_LISTPTR() static inline function to the internal C API.
