feat(dal-sink): support dynamic json handle mode

[KeXiangWang]

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

What's changed and what's your intention?

As titled.
Example:

CREATE sink test_sink as select id, name from test WITH (
    connector = 's3',
) FORMAT PLAIN ENCODE JSON(
    force_append_only='true', 
    jsonb.handling.mode = 'dynamic'
);

With dynamic, jsonb column will be expressed as json object instead string in the files on s3.

Added.

I tried. But we don't have existing tests for s3 sink with JSON format for now... Maybe leave it to a independent PR.
