switcherPopup: Bind to the stage, not the monitor

The switcher popup is a large, mostly transparent actor that
should cover all the clickable area of GNOME Shell. In Clutter
terms, it should cover the whole stage.

By binding it to the primary monitor, the Alt+Tab behavior
becomes a bit inconsistent. For example, by not hiding when
clicking at empty spaces at other monitors.

Fix that by binding the SwitcherPopup to the whole stage,
and not only the primary monitor.
