[gnome-builder/wip/gtk4-port] plugins/meson-templates: inherit AdwApplicationWindow

[Christian Hergert <chergert src gnome org>]

commit 63f201ebfba03638c492ab69a5fa8cba7228980e
Author: Christian Hergert <chergert redhat com>
Date:   Tue Jun 7 20:13:24 2022 -0700

    plugins/meson-templates: inherit AdwApplicationWindow
    
    If using libadwaita, inherit from AdwApplicationWindow instead.
    
    Clearly this all points out that we need a way to add patterns to an
    application eventually.
