Description
Running the quickitems example now gives this when exiting: (here was run with Vulkan + QSG_RHI_DEBUG_LAYER=1 + QT_RHI_LEAK_CHECK=1)

Actually this is not new. It's because what https://codereview.qt-project.org/c/qt/qtquick3d/+/339852 tried to fix, but then was never revisited: some
backend nodes, here the QSSGRenderItem2D, are not destroyed (the destructor never runs), hence the objects owned by it are leaked too.
