### 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.
### Does this PR introduce _any_ user-facing change?
No, dev-only.

### What changes were proposed in this pull request?
This PR aims to add a benchmark suite for nested predicate pushdown with parquet file:
Performance comparison: Nested predicate pushdown disabled vs enabled, with the following queries scenarios:
1. When predicate pushed down, parquet reader are able to filter out all the row groups without loading them.
2. When predicate pushed down, parquet reader only loads one of the row groups.
3. When predicate pushed down, parquet reader can't filter out any row group in order to see if we introduce too much overhead or not when enabling nested predicate push down.
### Why are the changes needed?
No benchmark exists today for nested fields predicate pushdown performance evaluation.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Benchmark runs and reporting result.
Closes#28319 from JiJiTang/SPARK-31364.
