For interface types, t.Methods contains only unexpanded method set, i.e
exclusive of interface embedding. Thus, we can't use it to detect an
interface contains embedding empty interface, like in:
type EI interface{}
func f() interface{ EI } {
return nil
}
At the time we generate runtime types, we want to check against the full
method set of interface instead.
Fixes #46386
