ftxui::Ref<> is used for passing Options, for instance, MenuOption, to the corresponding component which is supposed to hold a strong reference of it. and we can observe the events sent to the component by setting callback(s) in the option instance passed to the owner component. but the callback function is not always copyable, despite that it might be moveable. in this change, * Make<>() is updated to use the perfect forwarding to avoid enforcing its parameters to be copyable. * Ref<> is also updated to take a rvalue reference, so we can move away from the contructor parameter when creating an instance of Ref<>() from it.
