[mutter/gbsneto/more-screencast: 7/8] monitor-stream-src: Generalize function

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

    monitor-stream-src: Generalize function
    
    We'll need to pass a custom callback to the stage views watcher.
    Generalize and rename the add_view_painted_watches() function
    to allow accepting custom callbacks.
