Some, but not all scripts report "load time" for stateless engines (time to download parquet and sync)

While reviewing recent DataFusion results, I found there is now a "load time" reported for DataFusion

For example, this [link](https://benchmark.clickhouse.com/#system=+drB|erDt|ti%20rud&type=-&machine=+ca4e&cluster_size=-&opensource=-&hardware=+c&tuned=+n&metric=combined&queries=-)

Here is the source file that has 17:
https://github.com/ClickHouse/ClickBench/blob/a377499b950b17b2d96b79625375d57b18a36634/datafusion-partitioned/results/20260511/c6a.4xlarge.json#L10

It was added in https://github.com/ClickHouse/ClickBench/commit/6d5ee0a68573bbb481fdb8f799cc3348a9bb0634 which was part of a large refactoring in https://github.com/ClickHouse/ClickBench/pull/860

I am not sure if you intended the load_time to include the download / fsync time for the raw parquet dataset, but if you did I would request that we measure it consistently across stateless engines
