QWidget: Store initialScreen as QPointer
A Toplevel QWidget can hold a pointer to the screen where it will
eventually show contents, before a QWidgetWindow is created which then
takes precedence.
The screen member of QWindows is always kept up-to-date when a screen is
removed, but not the contents of a toplevel window. If a widget has
setScreen called but is never shown, it has potentially dangling pointer
which can cause issues in the future.
Pick-to: 6.8 6.7 6.5
