Fix the commit duplication issue in the DynamicIcebergSink caused by a race condition during recovery from a failed commit to the REST catalog. Validate that no new parent snapshot fetched from a refresh operation in the SnapshotProducer has a committed checkpoint ID higher than or equal to the currently staged committable. Throw an exception if a duplicate snapshot is detected to let the Flink job retry and skip the new request. Add unit and integration tests to replicate the commit duplication.

This PR is an alternative solution to #14425, which uses the same idea of checking duplicate concurrent commits using snapshot validation, similar to #14445.
The current solution extends
BaseRowDeltaandBaseReplacePartitionsoperations in Flink packages instead of adding public API methods toRowDeltaandReplacePartitionsinterfaces in #14445.
