Distinguish between menus in ActionBar and popup.

Mark the menus in the ActionBar and the ones in the Overflow popup
separately. This enables the IDE to differentiate between the two and
enable gestures such as double-click to open the menu xml for menus in
the ActionBar and single click for the menus in the Overflow popup.
