[FLINK-8538] [table] Add a Kafka table source factory with JSON format
## What is the purpose of the change
This PR is a continuation of #5505. Since this is the first connector with
format, time attributes, and table source factory, I encountered many
inconsistencies that I try to fix in this PR.
## Brief change log
- Change property `connector.version` to `connector.property-version` in
order to use `version` for things like Kafka
- Add more utility functions for better Java<->Scala interoperability
- Add full rowtime support
- Derive JSON mapping from schema
- Derive schema from source if required
## Verifying this change
Various unit tests implemented.
