refactor(streaming): top_n managed state use impl Row2

[wcy-fdu]

I hereby agree to the terms of the Singularity Data, Inc. Contributor License Agreement.

What's changed and what's your intention?

#6404 has introduced row trait, and StateTable insert/delete with impl Row2. This PR changes top_n managed state insert function to pass RowRef instead of Row.

Note that as we have not think clearly how to handle CompactedRow and Row2, it's hard for top_n managed state to delete RowRef now.

Checklist
