gh-111138: Add PyList_Extend() and PyList_Clear() functions (#111862)

Browse source 
* Split list_extend() into two sub-functions: list_extend_fast() and
  list_extend_iter().
* list_inplace_concat() no longer has to call Py_DECREF() on the
  list_extend() result, since list_extend() now returns an int.
