[epiphany/wip/exalm/tabs: 2/6] Merge TabHeaderBar into PagesView

[Alexander Mikhaylenko <alexm src gnome org>]

commit cfee657b63037db719c8e16c50de2c1fca68d7ff

    Merge TabHeaderBar into PagesView
    
    This change does regress the UI a little by introducing a duplicate header
    bar in the pages view. This will be fixed in the next commit, otherwise the
    change would be very massive.
