tdf#148115 Qt handle tooltips via event loop

Instead of calling QToolTip::showText directly from LO, this
defers showing the tooltip to the QEvent processing, which takes
the tooltip timeouts into account. So tooltips are shown with
a slight delay, therefore they happen less fast on mouse move,
reducing / avoiding artifacts of fast changing windows.

This unfortunately comes with yet an other hack in the area of
our fake popup windows...

New handling is based on the code of the Qt Tool Tips example.
