Make facet types complete like other types. This means that in the body of an interface, the type of `Self` is incomplete. This involved fixing an issue where eval of a specific_id that was already canonical was not resolving the specific declaration, which could occur as part of substituting into a facet type. --------- Co-authored-by: Josh L <josh11b@users.noreply.github.com> Co-authored-by: Richard Smith <richard@metafoo.co.uk> Co-authored-by: Dana Jansens <danakj@orodu.net>
