Now that WildFly main no longer supports building with Java 11 we need to either drop support for Java 11 or we need to test against an older version of WildFly.

Since we are not quite ready to drop Java 11 support this issue will update the CI scripts to not clone and build WildFly when the JDK version is less than 17 and to use WildFly latest otherwise.

Some axes (XTS, RTS etc) build our own jboss-as 6_BRANCH and these axes can only run on JDK 17 or above.

Also note that WildFly uses the maven-enforcer-plugin to verify that the Java is in the range [17,)
