patch 9.0.2036: if_python: rework python3.12 build dependency
Problem: if_python: rework python3.12 build dependency
(after 9.0.1996)
Solution: use PyTuple_Size instead of inlining the Py_SIZE
into the Vim code base
Use a simpler fix for Python 3.12 build issues
Python 3.12 introduced link dependencies to their `Py_SIZE()` inline
function, which #13290 fixed by copying the inline function to Vim's
Python binding code. This works but it's fragile, as a future update may
change the implementation of `Py_SIZE` and there is no way for us to
know.
The reason we need `Py_SIZE` to begin with is that we use
`PyTuple_GET_SIZE()` which calls that. Just fix it by mapping that to
(confusingly similarly named) `PyTuple_Size()`, which we already do in
the stable ABI implementation. There's a minor performance cost in that
it's not inlined and it does error checking but that's fine as we only
call this function rarely (in an error handler).
