We need add validations for FlinkTableSink that first_row table doesn't supports UPDATE/DELETE and partial-update! And add tests to verify that.

Table xxx uses the 'first_row' merge engine, which does not support DELETE or UPDATE statements.

LGTM. @luoyuxia I appended a commit to improve the config operations:
- Move
MergeEngineout ofConfigOptions, as it is very widely used in the code base, just likeKvFormat. - use
toFlinkOptionfor quick/easy conversion from Fluss ConfigOption to Flink ConfigOption, avoid duplicate definition inFlinkTableFactory.
