Does `RawWindowHandle` need to be `Copy`?

[grovesNL]

It looks like the Copy derive was added in #18, I guess because each handle happened to be compatible with it at the time.

However there are some benefits to removing Copy, e.g. it makes it possible to include strongly typed web handles that are reference counted (not Copy) #134 (comment)

My vote would be that it doesn't need to be Copy.

People should be paying close attention to code using these values and an occasional .clone() won't hurt them

I like the idea of a window/display handle having the same semantics as an &T reference. However I'd not married to this idea, so if the general consensus is to remove Copy I would be all for it.

Yeah, don't see nothing wrong with it.
