    window: Emit a11y signals directly on popover added/removed
    
    As those are internal children, there's no signal that GtkWindowAccessible
    could catch when those are added or removed, so make GtkWindow use the private
    GtkContainerAccessible methods to add/remove the child accessible when that
    happens.
