Liang-Chi Hsieh 93139afb07 [SPARK-26337][SQL][TEST] Add benchmark for LongToUnsafeRowMap
## What changes were proposed in this pull request?

Regarding the performance issue of SPARK-26155, it reports the issue on TPC-DS. I think it is better to add a benchmark for `LongToUnsafeRowMap` which is the root cause of performance regression.

It can be easier to show performance difference between different metric implementations in `LongToUnsafeRowMap`.

## How was this patch tested?

Manually run added benchmark.

Closes #23284 from viirya/SPARK-26337.
