…ent for FLIP-27 source
## What is the purpose of the change
For some split assignment strategy, the enumerator/assigner needs to track
the completed splits to advance watermark for event time alignment or rough
ordering. Right now, `RequestSplitEvent` for FLIP-27 source doesn't support
pass-along of the `finishedSplitIds` info and hence we have to create our own
custom source event type for Iceberg source.
