implemented sending split completed events over to Kafka

[domnikl]

Description

Issue: https://github.com/trinodb/trino/issues/23065

Implements sending SplitCompletedEvents to Kafka in the event listener plugin. By default those will not be sent to keep the current behavior of only sending query created and query completed.

Additional context and related issues

Example plugin configuration (extended with the new values for split completed):

event-listener.name=kafka-event-listener
kafka-event-listener.publish-created-event=false
kafka-event-listener.publish-completed-event=true
kafka-event-listener.publish-split-completed-event=true
kafka-event-listener.completed-event.topic=query_completed
kafka-event-listener.split-completed-event.topic=split_completed
kafka-event-listener.client-id=dominik.liebler.test
kafka-event-listener.broker-endpoints=kafka-host-1:9093,kafka-host-2:9093
kafka-event-listener.excluded-fields=ioMetadata,payload,groups,cpuTimeDistribution
