REVISION SUMMARY
  This fixes tooltips on Wayland. We need the relationship to the
  transient parent window - tooltips are positioned relative to their
  parent window. Also on X11 this is an important information which was
  completely lacking.
  
  Before the change the tooltips got randomly positioned by the Wayland
  compositor as it thought that it is a new toplevel window. With the
  change the tooltip gets shown where it is supposed to be shown.

TEST PLAN
  Run kinfocenter with --platform wayland and xcb

REPOSITORY
  rKINFOCENTER KInfoCenter
