Summary

Add a new enum constant RELEASE_13 to javax.lang.model.SourceVersion for the JDK 13 release and update the FooVisitor9 visitors to cover release 13 as well.

Problem

The SourceVersion enum needs an enum constant for each release being modeled.

Solution

Append the enum constant RELEASE_13 and update the visitor text and supported source version annotations to cover from RELEASE_9 to RELEASE_13.
