Fixes #119625.

The first commit fixes the infinite recursion and makes the cycle error actually show up. We do this by making the Display for ty::Instance impl respect with_no_queries so that it can be used in query descriptions.

The second commit fixes the cycle error resolver_for_lowering -> normalize -> resolve_instance (for evaluating const) -> lang_items (for drop_in_place) -> resolver_for_lowering (for collecting lang items). We do this by simply skipping the suggestion when encountering an unnormalized type.

fix cyle error when suggesting to use associated function instead of constructor

Fixes rust-lang#119625.

The first commit fixes the infinite recursion and makes the cycle error actually show up. We do this by making the `Display` for `ty::Instance` impl  respect `with_no_queries` so that it can be used in query descriptions.

The second commit fixes the cycle error `resolver_for_lowering` -> `normalize` -> `resolve_instance` (for evaluating const) -> `lang_items` (for `drop_in_place`) -> `resolver_for_lowering` (for collecting lang items). We do this by simply skipping the suggestion when encountering an unnormalized type.
