[SAMZA-2573] Ensure the top level order column feeding into the sql translation matches Schema

[b-slim]

Issues: Currently the order of Samza SQL schema and actual physical row coming from Samza is not guarantee to be correct aka the same. That is because the Schema injection layer is totally disconnected form the translation layer. Changes: This work add a map phase to ensure that the order is as expected between the Row Signature and the actual physical row. Tests: To test this I have shifted the order of __key__ and run all the test to made sure it works.
