provide a modern way to create signal dynamically

[exhaust-pipe]

I've recently been trying to create signals dynamically. The current method seems to be a two-step process: first, use Object.add_user_signal("my_signal"), and then create a reference to it with Signal(my_object, "my_signal") to get a usable Signal instance. This was the solution I found on Reddit (What is the constructor of the Signal class useful for?).

As a user in that thread pointed out, if it's possible to do this in multiple lines, it would be much better for Godot to provide a direct way to create a new signal. (he came up with the idea of a new Signal constructor)

My suggestion is to make Object.add_user_signal() return a Signal instance. This would turn a workaround into a clean, one-line method call:

var new_signal = my_object.add_user_signal("my_dynamic_signal")

This would be a great improvement for anyone working with dynamic signals.
