RFR JDK-8209896: [lworld] IncompatibleClassChangeError thrown when defining a lambda within value type

[mandy chung]

The lambda proxy generator currently generates ValueTypes attribute
to list the value types that are declared in parameter types and
return type.  But it misses the case when a lambda body is defined
in a value class but no value type declared in its signature.

This is a simple fix in InnerClassLambdaMetafactory.  I added
the test cases for lambda, core reflection, and method handles.
