feat(bar): hide when leaving komorebi's virtual desktop

This commit adds a new VirtualDesktopNotification which is used to
notify subscribers when the user leaves and enters the virtual desktop
associated with komorebi.

komorebi-bar consumes these notifications to minmize and restore the bar
appropriately depending on the currently focused virtual desktop.
