### 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

String res = s;
	bool carry = res.length() > 0;

		if (!carry) {
			break;
		}
		char32_t n = s[i];
		if (n == '9') { 
			res[i] = '0';
		} else {
			res[i] = s[i] + 1;
			carry = false;
		}
	}
	if (carry) {
		res = "1" + res;
	}
	return res;
