* gtk/Gtk.metadata : hide Object and Widget.Destroy.
	* gtk/Object.custom : manual virtual Destroy impl.
	* gtk/Widget.custom : manual virtual Destroy impl.
	* gtk/Window.custom : hold a managed ref for all toplevels. Release
	it in a Destroy override.  Window is frequently subclassed and is
	never parented, so this keeps a managed ref around to avoid GC.
	[Fixes #70120]

Equivalent to <see cref="M:Gtk.Object.Destroy" />, except that you don't have to cast the <paramref name="widget" /> to <see cref="T:Gtk.Object" />. When a <paramref name="widget" /> is destroyed, it will break any references it holds to other objects. If the <paramref name="widget" /> is inside a container, the <paramref name="widget" /> will be removed from the container. If the <paramref name="widget" /> is a toplevel (derived from <see cref="T:Gtk.Window" />), it will be removed from the list of toplevels, and the reference GTK+ holds to it will be removed.
