…eaded build Add special cases for classmethod and staticmethod descriptors in _PyObject_GetMethodStackRef() to avoid calling tp_descr_get, which avoids reference count contention on the bound method and underlying callable. This improves scaling when calling classmethods and staticmethods from multiple threads. Refactor method_vectorcall in classobject.c into a new _PyObject_VectorcallPrepend() helper so that it can be used by by PyObject_VectorcallMethod as well.
