[gnome-shell/wip/aggregate-menu: 25/58] popupMenu: Remove column widths

    popupMenu: Remove column widths
    
    This code is too complicated to keep, and the last straw came after the
    fixed width menu in the aggregate menu design.
    
    This will break some existing popup menus that rely on the fixed width,
    but this will soon be replaced with the aggregate menu. We'll also soon
    clean this up further by replacing PopupBaseMenuItem's custom layout code
    with an StBoxLayout.
