Add SourceVersion.RELEASE_18

Summary

Add a new enum constant RELEASE_18 to javax.lang.model.SourceVersion for the JDK 18 release and update the FooVisitor14 visitors to cover release 18 as well.

Problem

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

Solution

Append the enum constant RELEASE_18 and update the visitor text and supported source version annotations to cover from RELEASE_14 to RELEASE_18.
