dbusmenu: Use proper toggle-type for items that are part of group

To achieve that, add a new virtual setHasExclusiveGroup() method to
QPlatformMenuItem class (optional because we don't want to break existing
platform themes), call it when converting QActions into platform menu items,
and use it when exporting the menu items over D-Bus.

Also, send ActionChanged event for actions when their group is changed, so
that the platform menus are updated too.
