[Feature] Support for Kafka CDC parsing `debezium-avro-confluent` format data

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.

### Motivation

In our production environment, Kafka is mostly used to store data in Avro format, in conjunction with the `Confluentinc/Schema-Registry`.

The issue does not name any files, tests, or entry points, and provides no implementation details beyond Kafka CDC data in the debezium-avro-confluent format. Start by locating the existing Kafka CDC parsing paths and format handlers; done should mean that this format is parsed successfully with coverage for its expected data.
