tdf#125692 SalObject always holds a SystemChildWindow
Let's just face reality and store it as a VclPtr.
And this is needed, because Qt, like VCL, uses deferred deletion,
and has no way to filter events to QObjects out of its event queue
easily. This way the qt5 plugin can report focus changes for
SalObjects without a crash, which happens when you close a
presentation with a video by click.
And in addition it reverts the workaround introduced in commit
e770bacc85a0 ("Qt5 workaround modal change after show bug"), as it
seems this bug is a use-after-free error, introduced by LO.
Thanks Michael Weghorn for catching that!
Maybe someone should also rename SalObject...
