Python 3.12: Fix the structure of class property

There is a PySide bug in Python 3.10 already: The structure for
classproperty derives from the property structure. This was extended
in Python 3.10, already, but the type generation check was made more
exhaustive in Python 3.12 and recognized that.

This change is only for making the compiler/C API happy.
In order to use the extension field, it is necessary to do a runtime
check because of the Limited API.
