Subject: [PATCH] Update pyside2/shiboken2 and sip4 to Python 3.12

These are both Python QT 5 modules, which have issues with Python 3.12
that are fixed in never versions, yet many packages depend on them.

Sip4 was as simple as installing and switching over to setuptools (to
replace the now removed distutils).

pyside/shiboken was much more involved. I ended up pulling the required
patches from the Ubuntu release repositories. The existing patch to fix
clang's include headers needed an update as well, but was still
required.

There is some unsightly find-and-replace going on to replace distutils
with setuptools. This is because, although setuptools now creates the
"distutils" import module, it has to be itself imported first before
that can happen. I Used this widespread find-and-replace as it does
function properly, and should be extremly flexable for future versions
(no needing to update patches on each release).

+Subject: 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.

+Subject: Support running PySide on Python 3.12
+
+Builtin types no longer have tp_dict set. We need to
+use PyType_GetDict, instead. This works without Limited API
+at the moment.
+
+With some great cheating, this works with Limited API, too.
+We emulate PyType_GetDict by tp_dict if that is not 0.
+Otherwise we create an empty dict.
+
+Some small changes to Exception handling and longer
+warm-up in leaking tests were found, too.

+Subject: shiboken2/clang: Record scope resolution of arguments/function
+ return
+
+Add a flag indicating whether a type was specified with a leading "::"
+(scope resolution). Such parameters previously caused the function to
+rejected due to the "::TypeName" not being found. The type resolution
+added for clang 16 strips these qualifiers though, so, the information
+needs to be stored.
+
+Task-number: PYSIDE-2288

+Subject: shiboken2/clang: Write scope resolution for all parameters of native
+ wrappers
+
+Make sure types are correct for cases like:
+
+- QtDBusHelper::QDBusReply::QDBusReply(::QDBusReply<void>)
+- Qt3DInput*Event constructors taking the equivalent QtGui classes
+  (Qt3DInput::QMouseEvent(::QMouseEvent *);
+
+[ChangeLog][shiboken6] Support for parameters/function return
+types with scope resolution has been improved.
+
+Fixes: PYSIDE-2288
+Pick-to: 6.5 5.15
+Change-Id: Id29758fceb88188f4cd834fbd5a7cc0ab511fb1a
+Reviewed-by: Christian Tismer <tismer@stackless.com>
