cros: Anchor touch and mouse menus similarly.

Per UX request, anchor all application/context menus the same (based on
the app icon).

Previous behavior was to anchor mouse menus based on the click point,
the new behavior anchors the menu based on the app icon regardless
of whether the event summoning the menus is touch or click.

cros: anchor touch and mouse menus the same

As per request from ux, anchor touch and mouse menus similarly.

Previously touch menus were anchored based on the app icon,
and mouse menus were anchored on the click point.

Now we will anchor all menus on the app icon.
