[gnome-builder/wip/gtk4-port] plugins/valac: replace vala-pack with valac plugin

[Christian Hergert <chergert src gnome org>]

commit c65cf62d56cc5c24bb96cfd8f9f5be5aa3e9b888

    plugins/valac: replace vala-pack with valac plugin
    
    This removes the vala-pack plugin which combined a pipeline error regex
    with an indenter. Since indenters will come from GtkSourceView in the
    GTK 4 port, we can just drop the indenter and focus on the error regex.
    
    That can be a more specialized "valac" plugin similar to the mono plugin
    for mcs/gmcs error output.
