Kent Yao 54996be4d2 [SPARK-31527][SQL][TESTS][FOLLOWUP] Add a benchmark test for datetime add/subtract interval operations 
### What changes were proposed in this pull request?
With https://github.com/apache/spark/pull/28310, the operation of date +/- interval(m, d, 0) has been improved a lot.

According to the benchmark results, about 75% time cost is reduced because of no casting date to timestamp back and forth.

In this PR, we add a benchmark for these operations, and timestamp +/- interval operations as accessories.

### Why are the changes needed?

Performance test coverage, since these operations are missing in the DateTimeBenchmark.

### Does this PR introduce any user-facing change?

No, just test

### How was this patch tested?

regenerated benchmark results

Closes #28369 from yaooqinn/SPARK-31527-F.
