Port tooltips to KToolTipWidget

Use the new KToolTipWidget class (introduced by kwidgetsaddons 5.30) as backend of ToolTipManager.
FileMetaDataToolTip becomes a simple widget used as content of the tooltip.

It is now possible to actually use the metadata widget shown inside the tooltips.
Tooltips are now functional on Wayland as well.
