[SPARK-29192][TESTS] Extend BenchmarkBase to write JDK9+ results separately ### What changes were proposed in this pull request? This PR aims to extend the existing benchmarks to save JDK9+ result separately. All `core` module benchmark test results are added. I'll run the other test suites in another PR. After regenerating all results, we will check JDK11 performance regressions. ### Why are the changes needed? From Apache Spark 3.0, we support both JDK8 and JDK11. We need to have a way to find the performance regression. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Manually run the benchmark. Closes #25873 from dongjoon-hyun/SPARK-JDK11-PERF. Authored-by: Dongjoon Hyun <dhyun@apple.com> Signed-off-by: Dongjoon Hyun <dhyun@apple.com>
