Implement pyside6 style properties #1275
Description
What's the problem this feature will solve?
need to implement pyside6 'property' declarations alongside the pyqt5 way.
pyside6 property declarations should be done like this: https://doc.qt.io/qtforpython-6/PySide6/QtCore/Property.html
i think this should also fix the rendering issues with examples/drawing/drawing_demo.ui (should render the same as pyqt5)
Describe the solution you'd like.
for now, the code should support pyqt5 or pyside6 properties (https://doc.qt.io/qtforpython-6/PySide6/QtCore/Property.html) depending on what wrapper is currently enabled (set by QT_API=...)
this probably will have to be done using qt-wrapper conditional checks as are already in the codebase:
if ACTIVE_QT_WRAPPER == QtWrapperTypes.PYSIDE6: etc...
