Override `Waker::clone_from` to avoid cloning `Waker`s unnecessarily

This would be very useful for futures — I think it’s pretty much always what they want to do instead of `*waker = cx.waker().clone()`.

I think this is obsolete since #96979 switched to overriding clone_from.

@cuviper cuviper closed this as not planned Won't fix, can't repro, duplicate, stale Dec 5, 2023
