[b]Note:[/b] It is not possible to switch physics servers at runtime. This class is only used on startup at the server initialization level, by Godot itself and possibly by GDExtensions.
Register a [PhysicsServer2D] implementation by passing a [param name] and a [Callable] that returns a [PhysicsServer2D] object.
