Get ROW_ID from search() in Infinity (#13901)

### What problem does this PR solve?

1. Search() in Infinity can return row_id now

2.  To Get ROW_ID from search(), refer to handling of retrieval_test.

example
```
$ curl -s -X POST "http://localhost:$PORT/v1/chunk/retrieval_test" -H "Authorization: $TOKEN" -H "Content-Type: application/json" -d '{"kb_id": "4fcd01582ca911f1954184ba59049aa3", "question": "曹操"}'
```
