Only close popup in the the hierchary

Imagine following event sequences:
1. a tooltip is shown. activePopups = {tooltip}
2. user click menu bar to show the menu, QMenu::setVisible is called.
    now activePopups(tooltip, menu}
3. tooltip visibility changed to false.
4. closePopups() close both tooltip and menu.

This is a common pattern under wayland that menu is shown as a invisible
state. This patch tries to memorize the surface hierchary used to create
the popup role. And only close those popups whose ancesotor is hidden.
