[FLINK-37336][python] Introduce TablePipeline descriptor to Python Table API

[autophagy]

What is the purpose of the change

Currently, the TablePipeline descriptor is not supported in the Pyflink Table API, so API methods such as insert_into on a table environment are subsequently not supported. This PR introduces the TablePipeline descriptor so that users can setup a table pipeline, explain it, execute it, etc. (Please ignore the branch name, I got my JIRA Ids mixed up 😅)

Brief change log

• Introduced TablePipeline descriptor.
• Introduced the ObjectIdentifier catalog entity.
• Adds StatementSet.add to add a TablePipeline to the StatementSet.
• Adds Table.insert_into to declare a TablePipeline with a given table path or table descriptor.
