Previously, we handled recursive interfaces by deferring typechecking of interface methods, while eagerly expanding interface embeddings. This CL switches to eagerly evaluating interface methods, and deferring expanding interface embeddings to dowidth. This allows us to detect recursive interface embeddings with the same mechanism used for detecting recursive struct embeddings. Updates #16369.
