Subject: [PATCH] Set parentItem for pages in DockWindow

After https://invent.kde.org/qt/qt/qtdeclarative/-/merge_requests/40 a
QQuickItem without a parentItem is always invisible. While this avoids
some crashes in plasmashell, it breaks some applications like MuseScore
where pages don't have a parent item.

This is also important for Qt6 porting.

Fixes #17276
