fix: add missing nulls_not_distinct property to IndexStmt transformer

- Add nulls_not_distinct property handling in v15-to-v16 IndexStmt transformer
- Enable previously skipped CREATE INDEX test cases with NULLS NOT DISTINCT
- Fixes transformer failures for create_index-72.sql, create_index-83.sql, create_index-85.sql, create_index-184.sql
