REVISION SUMMARY

KWin always has a few internal windows around which are not visible.
A QWindow created somewhere, but not shown. Such windows should not
be part of the stacking order.

If they are it breaks code which looks at the top most window in the
stacking order like e.g. SlidebackEffect.

This change ensures that the stacking order gets updated whenever a
ShellClient gets hidden and that internal windows with isShown being
false are excluded from the stacking order.
