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 😄
