[Mac] Implement a basic overflow menu for hidden Browser Action buttons.

Known issues:
o The ordering of the Browser Actions is not consistent within the menu.
o Icons for the actions within the menu are not implemented yet.
o It is a standard NSMenu, so drag and drop will not work and right click does not work for now.
