Upgrade antlr to more current release

As per the bug that was reported here - https://hibernate.atlassian.net/browse/HHH-10028, Hibernate stays in-step with Wildfly and EAP dependency versions to ensure compatibility.

This task is a request to upgrade antlr to its latest version available against WildFly so that Hibernate also can pick the latest to be in synch with WildFly.

Hibernate (hibernate-core to be more specific) latest version is still using antlr version 2.7.7 released on Jan 13, 2007. The latest available, built and maintained version is antlr-4-Runtime 4.7.2. Another reason for going with latest of antlr is to avoid any security vulnerabilities that the library is exposed to.
