[gnome-builder/wip/gtk4-port] plugins/buildui: add busy state and setup actions

[Christian Hergert <chergert src gnome org>]

commit 26d98cf8e46f778c9e85044eb71779b94cb7e3e1

    plugins/buildui: add busy state and setup actions
    
    The action implementation is not there yet, but we can setup the rows to
    have the proper action/target as well as show a spinner for long running
    operations which might need to complete before we can display contents.
