In the types1 universe, we only need to represent value types. For
interfaces, this means we only need to worry about pure interfaces. A
pure interface can embed a union type, but the overall union must be
equivalent to "any".
In go.dev/cl/458619, we changed the types1 reader to return "any", but
to incorporate a consistency check to make sure this is valid.
Unfortunately, a pure interface can actually still reference impure
interfaces, and in general this is hard to check precisely without
reimplementing a lot of types2 data structures and logic into types1.
We haven't had any other reports of this check failing since 1.20, so
it seems simplest to just suppress for now.
Fixes#60117.

In the types1 universe under the unified frontend, we never need to
worry about type parameter constraints, so we only see pure
interfaces. However, we might still see interfaces that contain union
types, because of interfaces like "interface{ any | int }" (equivalent
to just "any").
We can handle these without needing to actually represent type unions
within types1 by simply mapping any union to "any".
Updates #57410.
