### 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

N/A
if ((this != p_original) && !(p_original->is_ancestor_of(this))) {
		return;
	}
	List<const Node *> process_list;
	process_list.push_back(this);
	while (!process_list.is_empty()) {
		const Node *n = process_list.front()->get();
		process_list.pop_front();
		List<Connection> conns;
		n->get_all_signal_connections(&conns);
		for (const Connection &E : conns) {
			if (E.flags & CONNECT_PERSIST) {
				//user connected
				NodePath p = p_original->get_path_to(n);
				Node *copy = p_copy->get_node(p);
				Node *target = Object::cast_to<Node>(E.callable.get_object());
				if (!target) {
					continue;
				}
