Avoid rehashing Fingerprint as a map key
This introduces a no-op `Unhasher` for map keys that are already hash- like, for example `Fingerprint` and its wrapper `DefPathHash`. For these we can directly produce the `u64` hash for maps. The first use of this is `def_path_hash_to_def_id: Option<UnhashMap<DefPathHash, DefId>>`.
