RFR (XS): 8014709 Constructor.getAnnotatedReturnType() returns empty AnnotatedType

[Joel Borggren-Franck]

Hi

Please review this fix and test update for 8014709:
Constructor.getAnnotatedReturnType() returns empty AnnotatedType.

When implementing VM support for reflection for type annotations I
forgot to store the type annotation byte array on
java.lang.reflect.Constructor objects. This is a fix and a test update
to address this.

Modified test fails with an old HotSpot passes with the fix.

This bug was found in internal testing that also passes with the fix.
