Hide ARC++ Windows with the same logical_window_id

Windows are considered one "logical window" if they are created
with the same |shelf_group_id| and |logical_window_id|.
The consequence: only one window per logical window is shown in
the shelf, the alt-tab menu, and the desk mini view.

The use case are windows across multiple screen, which are not possible
in Chrome OS. So the app creates one window per screen and marks them
as one logical window.

This is done by the |ArcAppWindowInfo|, which stores the IDs mentioned
above. It is setting the |HideInDeskMiniView| property, the
|HideInOverview| property and the new |HideInShelf| property on a
window. The AppWindowLauncherItemController pays attention to the
HideInShelf property and will not use hidden windows as
|last_active_window|s, nor return them via |GetAppMenuItems|.

When a window closes, it might have been the visible window of a
logical window, so the |AppServiceAppWindowArcTracker| checks this and
tells a different app of the same logical window to become visible.
