[oceanbase] Add new deserialization schema with runtime converter

[whhe]

The previous logic is to do the first conversion with OceanBaseJdbcConverter helper methods, and then use runtime converters in JdbcValueConverters to do the second conversion. Now we need only do conversion one time with the new deserialization schema.

@leonardBang please help to review this pr. The test failure seems not related to my modification, so I will not try to fix it.

Thanks for your work. I have left some comments. Besides these, I find that there are many duplicated code between the new code and the code in module flink-connector-debezium, e.g. AppendMetadataCollector. Is there a way to reuse them?

It's hard to reuse codes in RowDataDebeziumDeserializeSchema and AppendMetadataCollector in debezium module, because they both are final classes.
