Description

Generate the same code for the same logic, so that we may reuse the generated code between different jobs. This is the precondition for FLINK-28691. The current issue is we use a self-incrementing counter in CodeGenUtils#newName, it means we could not get the same generated class between two queries even when they are exactly the same.
