[gnome-builder/wip/gtk4-port: 936/1774] plugins/buildui: prototype select build target dialog

[Christian Hergert <chergert src gnome org>]

commit 3ec3bd3612ec8c4a5b506fcf1fd6b6a640d67636

    plugins/buildui: prototype select build target dialog
    
    This isn't finished, but I prefer to get things in early and iterate. It
    is just a window that we'll show to allow the user to select the default
    build target.
    
    It probably needs some whizbangs to show while it extracts content in case
    that operation is slow (ie: requires building or configuring some stuff).
    
    Also, we might want to allow a free-form target to be specified if the
    backend supports it.
