spinbutton: Make the entry gadget be the entry's gadget This is a big and somewhat evil hack: We replace the entry's gadget's node with the spinbutton's entry node.

gadget: Handle visibility As GtkCssNode has the visibility concept, it makes sense to mirror it in gadgets. Do what visibility does in widgets: Hidden gadgets can't be drawn or allocated and request a 0x0 size. Note that just like widgets, gadget visibility must not be changed in size request, allocate or draw handlers. GtkWidget::child-visible has no equivalent yet, code will have to emulate that manually.
