hygiene: Introduce a helper method for creating new expansions
Creating a fresh expansion and immediately generating a span from it is the most common scenario. Also avoid allocating `allow_internal_unstable` lists for derive markers repeatedly. And rename `ExpnInfo::with_unstable` to `ExpnInfo::allow_unstable`, seems to be a better fitting name.
