lihangyu 29dc08fc45 [Optimize](simd json reader) Cached search results for previous row (keyed as index in JSON object) - used as a hint. (#17124)
* [Optimize](simd json reader) Cached search results for previous row (keyed as index in JSON object) - used as a hint.

`_simdjson_set_column_value` could become a hot spot while parsing json in simdjson mode,
introduce `_prev_positions` to cache results for previous row (keyed as index in JSON object) due to the json name field order,
should be quite the same between each lines

* fix case
