[FLINK-31262][kafka] Move kafka sql connector fat jar test to SmokeKafkaITCase

[reswqa]

What is the purpose of the change

SmokeKafkaITCase only covered the application packaging test of datastream job, we should also bring this kind of test to sql job submitted by sql-client to cover the case of sql connector fat jar.
In fact, we already have similar test class with the same purpose, that is SQLClientKafkaITCase, but this test is ignored since 2021/4/20. It depend on the
LocalStandaoneKafkaResource which download kafka and sets up a local cluster, but we often encounter download failures in CI environments. Fortunately, now we prefer to use TestContainer in E2E test. So I suggest integrating the corresponding test logic into SmokeKafkaITCase, and then removing it

I see #22797 , this pr is no longer relevant to this repository, I suggest closing this pr and porting the change to the new Flink connector kafka repo if it is still relevant.

[reswqa]

Yes, I will close this.

@reswqa Will you move it to the other repo?

[reswqa]

Yes, but it may take some long time. I have been busy with other things recently. Before that, anyone interested can take over this.
