[gnome-shell] extensions-app: Move headerbar content to the main view

[Marge Bot <marge-bot src gnome org>]

    extensions-app: Move headerbar content to the main view
    
    With the new borderless style of libadwaita, the global switch in the headerbar
    did not look good. Moving it to the main view is the opportunity to also move
    the content of the information popover.
