shiboken reproducible builds issue

While working on reproducible builds for openSUSE, I found that
our python3-pyside2 package varies in every build
because the /usr/lib64/libshiboken2.cpython-311-x86_64-linux-gnu.so.5.15.10 varies in _ZL22PySide_SignatureLoader base64-encoded content.

In the build-env I cound see that
other_module_wrapper.cpp had ordering issues in a section labeled
// Extended implicit conversions for

and pyside-setup-opensource-src-5.15.10/build/sources/pyside2/PySide2/QtWidgets/PySide2/QtWidgets/qgridlayout_wrapper.h
// Inherited overloads

that is generated by sources/shiboken2/generator/shiboken2/headergenerator.cpp
