Window Switching layouts are not flickable over bounds

Flicking has to stop at the bounds in the window switcher
layouts. It's not natural on the desktop that they are
flickable in the first place.

Window Strip is unchanged as this layout is intended to be used
on touch and flickable user experiences.
