refactor(transformer/async-generator-functions): use clone not clone_in on LabelIdentifier (#7172)

Browse source 
Follow-on after stack up to #7148.

Small optimization. `LabelIdentifier` is `Clone` so we can use `Clone::clone` to clone it, instead of `CloneIn::clone_in`.

The difference is that `clone_in` makes a 2nd copy of the `Atom`'s string in the arena, whereas `clone` creates a new `Atom` referencing the same string. This is an unfortunate shortcoming of `CloneIn` (https://github.com/oxc-project/backlog/issues/96), but the more we can avoid `CloneIn`, the better.
