Summary

Add a new enum constant RELEASE_27 to javax.lang.model.SourceVersion for the JDK 27 release and update the FooVisitor14 and FooVisitorPreview visitors to cover release 27 as well.

Problem

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

Solution

Append the enum constant RELEASE_27 and update the visitor text and supported source version annotations to cover from RELEASE_14 to RELEASE_27. As a consequence of appending a new enum constant, the behavior of the latest() and latestSupported() methods is updated accordingly.
