Windows build fails with TypeError #99041
Description
Bug report
When building python 3.11 on windows, if the version of python already present for bootstrapping is too old, the build fails. This appears to be because find_python.bat only enforces that the python version is >=3.8 while deepfreeze.py uses 3.9 only features (and in fact, not hit upon here, when using a virtualenv the version of python is not in any way checked).
I am not sure if core devs would prefer that find_python.bat enforce python >=3.9 or that any 3.9 features be taken out of build tools for this release cycle.
Sample failure after running msbuild with %HOST_PYTHON% set specifically to C:\build\deps\python3.EXE which is version 3.8:
FindPythonForBuild:
"C:\build\deps\python3.EXE"
Using PythonForBuild="C:\ActiveState\APy\python3.EXE"
_RebuildDeepFrozen:
