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.

Fixes#18392.
Avoid nil dereferencing n.Right when dealing with non-existent
self referenced interface methods e.g.
type A interface{
Fn(A.Fn)
}
Instead, infer the symbol name from n.Sym itself.
