### Issue description

When you have binds set for a given signal in the editor and then duplicate the node with ctrl + D, it does not maintain the bind values; they are simply ignored. I can't imagine this is not a bug, so reporting it. If absolutely needed, I can produce a repro project for this, it's just very simple and probably an obvious bug somewhere in the duplication code.

### Steps to reproduce

1. Create a basic project. (One is not included because the issue requires actually doing the steps, rather than looking at what's there.)
2. Create a Node2D as the root of a scene. Give it an Area2D.
3. Add a script to the Node2D and connect the area_entered signal of Area2D to the Node2D's script, including one or more extra bound values in the advanced editor.
4. Duplicate the Area2D; note that the signal connections themselves are duplicated, but the binds array has not been.

### Minimal reproduction project

data.ready_notified = true;
	data.blocked++;

		K.value->_propagate_ready();
	}
	data.blocked--;
	notification(NOTIFICATION_POST_ENTER_TREE);
	if (data.ready_first) {
		data.ready_first = false;
		notification(NOTIFICATION_READY);
		emit_signal(SceneStringNames::get_singleton()->ready);
	}
}
void Node::_propagate_enter_tree() {
	
	if (data.parent) {
		data.tree = data.parent->data.tree;
		data.depth = data.parent->data.depth + 1;
	} else {
		data.depth = 1;
	}
	data.viewport = Object::cast_to<Viewport>(this);
