This CL changes cmd/compile to reject anonymous interface cycles like:
type I interface { m() interface { I } }
We don't anticipate any users to be affected by this change in
practice. Nonetheless, this CL also adds a `-d=interfacecycles`
compiler flag to suppress the error. And assuming no issue reports
from users, we'll move the check into go/types and types2 instead.
Updates #56103.
