test(connector): add kafka-cdc-sink compatible test

[xuefengze]

I hereby agree to the terms of the RisingWave Labs, Inc. Contributor License Agreement.

What's changed and what's your intention?

In Risingwave -(Debezium Json)-> Kafka -(Debezium Json)-> JDBC connector -> Postgresql pipeline:

• unsupport type: array, struct
• time, timestamp's precision is milliseconds, bug(sink): json encoder does not preserve microsecond precision #13564
• In our implementation, interval, decimal's schema type can't convert by Debezium JDBC, so just use text type in PG.

In Risingwave -(Debezium Json)-> Kafka -(Debezisum Json)-> Flink SQL --> Postgresql pipeline:
According to Flink, support types: boolean, smallint, integer, bigint, decimal, real, double precision, varchar, bytea.
