patch 9.0.1917: undefined behaviour with python function pointer
Problem: undefined behaviour with python function pointer
Solution: correctly cast function pointers from void
Fix more undefined behaviors in if_python
Fix remaining UBSAN errors from Clang 17 in if_python in casting
function pointers.
Also fix a mistake where `PyMem_Free()` should be returning void, by the
dynamic build is mistakenly casting it as a function that returns an
int.
