### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/32015 added a way to run benchmarks much more easily in the same GitHub Actions build. This PR updates the benchmark results by using the way.
**NOTE** that looks like GitHub Actions use four types of CPU given my observations:
- Intel(R) Xeon(R) Platinum 8171M CPU 2.60GHz
- Intel(R) Xeon(R) CPU E5-2673 v4 2.30GHz
- Intel(R) Xeon(R) CPU E5-2673 v3 2.40GHz
- Intel(R) Xeon(R) Platinum 8272CL CPU 2.60GHz
Given my quick research, seems like they perform roughly similarly:
I couldn't find enough information about Intel(R) Xeon(R) Platinum 8272CL CPU 2.60GHz but the performance seems roughly similar given the numbers.
So shouldn't be a big deal especially given that this way is much easier, encourages contributors to run more and guarantee the same number of cores and same memory with the same softwares.
### Why are the changes needed?
To have a base line of the benchmarks accordingly.

### What changes were proposed in this pull request?
This PR regenerate the benchmark results in `core` and `mllib` module in order to compare JDK8/JDK11 result.
### Why are the changes needed?
According to the result, For `PropertiesCloneBenchmark` and `UDTSerializationBenchmark`, JDK11 is slightly faster. In general, there is no regression in JDK11.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
This is a test-only PR. Manually run the benchmark.

### 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.
