[gnome-builder/wip/gtk4-port] plugins/sysprof: implement opening of sysprof captures

[Christian Hergert <chergert src gnome org>]

commit f399ffa489372162708f9b7b1272d7b9d31dde76

    plugins/sysprof: implement opening of sysprof captures
    
    This adds a new page type which just displays the capture contents. We
    still need something to do the actual recording widget though (or at least
    show the number of events recorded in the status bar or something).
