[nautilus/wip/antoniof/gtk4-preparation-discontinued-api: 15/19] general: Don't subclass GtkInfoBar


commit 8208d193416d02578399f9095cce51d3a77b2363
Author: António Fernandes <antoniof gnome org>
Date:   Sun Dec 19 12:51:53 2021 +0000

    general: Don't subclass GtkInfoBar
    
    It's going to be a final class one we switch to GTK 4.
    
    In preparation, become bins containing an info bar.
    Also, stop using gtk_info_bar_get_action_area(), which is gone in GTK 4
    and we are using it only to set the box to horizontal orientation,
    which is the default anyway.
