[FLINK-8537][table]Add a Kafka table source factory with Avro format support
## What is the purpose of the change
This PR adds the Kafka table source factory with Avro format.
## Brief change log
### Adding
- Add an `Avro` format descriptor and the corresponding validator.
- Add a `KafkaAvroTableSourceFactory` and its version specific
implementations.
- Add a `KafkaTableSourceFactory` and make the json/avro factory extend
it.
- Add `equals()` and `hashCode()` methods to the timestamp/watermark
extractors for testing.
### Updating
- Change the schema configuration logic for `KafkaJsonTableSourceFactory`.
- Add a `withFormat` flag to `KafkaJsonTableSourceFactory` test cases and
replace the proctime attributes with the rowtime ones.
- Move the `convertToRowTypeInformation()` method to a new helper class
`AvroTypeInfoConverter`.
### Dependency
- Make `flink-avro` depend on `flink-table` and `flink-streaming-scala`.
- Remove the `flink-avro` dependency from `flink-table` and move the only
effcted test `AvroTypesITCase` to `flink-avro`.
## Verifying this change
This change can be verified by the test cases in `AvroTest` and
`KafkaAvroTableSourceFactoryTestBase`.
