Rollup merge of #72499 - mendess:master, r=dtolnay
Override Box::<[T]>::clone_from Avoid dropping and reallocating when cloning to an existing box if the lengths are the same. It would be nice if this could also be specialized for `Copy` but I don't know how that works since it's not on stable. Will gladly look into it if it's deemed as a good idea. This is my first PR with code, hope I did everything right :smile:
