[New-bugs-announce] [issue46323] Use _PyObject_Vectorcall in Modules/_ctypes/callbacks.c

New submission from hydroflask <hydroflask at yqxmail.com>:

_CallPythonObject() in Modules/_ctypes/callbacks.c still uses the old API (PyObject_CallObject()) to invoke methods. It should use _PyObject_Vectorcall(). Creating an issue for this since this method is a little more performance sensitive than normal Python library code.
