The JDK team has completely disabled the Java SecurityManager from Java 24. Elasticsearch has always used the Java SecurityManager as an additional protection mechanism; in order to retain this second line of defense, the Elasticsearch Core/Infra team has been working on the Entitlements project. Similar to SecurityManager, Entitlements only allow calling specific methods in the JDK when the caller has a matching policy attached. In other words, if some code (in the main Elasticsearch codebase, in a plugin/module, or in a script) attempts to perform a "privileged" operation and it is not entitled to do so, a NotEntitledException will be thrown. This PR includes the minimal set of changes to always use Entitlements, regardless of system properties or Java version. Relates to ES-10921
