patch 9.0.1996: Cannot build with python312

Browse Source 
Problem:  Cannot build with python312
Solution: Define wrapper types and functions for python 3.12

Py_SIZE() uses PyLong_Type and PyBool_Type starting from Python 3.12.
We need to define our own Py_SIZE() to replace Py{Bool,Long}_Type with
py3_Py{Bool,Long}_Type.
We also need to redefine PyTuple_GET_SIZE() and PyList_GET_SIZE(), because
they use Py_SIZE().
