jakarta.persistence.EntityListener XML declaration

[sebersole]

Possible solution to #1148. This option uses in-line repeatable elements following the lead from other repeatable elements in this XSD. E.g.

<persistence ...>
    <persistence-unit ....>
        <class>com.acme.A</class>
        <class>com.acme.B</class>

        ...

        <entity-listener>com.acme.Journaler</entity-listener>
        <entity-listener>com.acme.PermissionChecker</entity-listener>
    </persistence-unit>
</persistence>

LGTM, after the change I suggest below.

maybe worth having some quick test next to

persistence/tck/spec-tests/src/main/java/ee/jakarta/tck/persistence/jpa40/emflistener/PersistenceUnitLifecycleClient.java

Line 35 in 469e7e4

public class PersistenceUnitLifecycleClient extends PMClientBase {
