Summary: We look up the identities corresponding to slot index from raw_id_tracker and forward it to TBE. The identities are stored in raw_id_tracker during mc_module lookup. raw_ids are retrieved per-table from raw_id_tracker with the api get_indexed_lookup(), we concatenat them to maintain 1-to-1 alignment with features.values().
