cmd/compile/internal/types2: use correct recv for parameterized embedded methods Methods of generic types are instantiated lazily (upon use). Thus, when we encounter a method of such a type, we need to instantiate the method signature with the receiver type arguments. We infer those type arguments from the method receiver. If the method is embedded, we must use the actual embedded receiver type, otherwise the receiver type declared with the method doesn't match up and inference will fail. (Note that there's no type inference in the source code here, it's only the implementation which uses the existing inference mechanism to easily identify the actual type arguments. If the implementation is correct, the inference will always succeed.) Updates #44688.
