### 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.

### What changes were proposed in this pull request?
Add benchmarks for interval constructor `make_interval` and measure perf of 4 cases:
1. Constant (year, month)
2. Constant (week, day)
3. Constant (hour, minute, second, second fraction)
4. All fields are NOT constant.
The benchmark results are generated in the environment:

### What changes were proposed in this pull request?
In the PR, I propose to replace `.collect()`, `.count()` and `.foreach(_ => ())` in SQL benchmarks and use the `NoOp` datasource. I added an implicit class to `SqlBasedBenchmark` with the `.noop()` method. It can be used in benchmark like: `ds.noop()`. The last one is unfolded to `ds.write.format("noop").mode(Overwrite).save()`.
### Why are the changes needed?
To avoid additional overhead that `collect()` (and other actions) has. For example, `.collect()` has to convert values according to external types and pull data to the driver. This can hide actual performance regressions or improvements of benchmarked operations.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Re-run all modified benchmarks using Amazon EC2.

### What changes were proposed in this pull request?
With the latest string to literal optimization https://github.com/apache/spark/pull/26256, some interval strings can not be cast when there are some spaces between signs and unit values. After state `PARSE_SIGN`, it directly goes to `PARSE_UNIT_VALUE` when takes a space character as the end. So when there are some white spaces come before the real unit value, it fails to parse, we should add a new state like `TRIM_VALUE` to trim all these spaces.
How to re-produce, which aim the revisions since https://github.com/apache/spark/pull/26256 is merged
```sql
select cast(v as interval) from values ('+ 1 second') t(v);
select cast(v as interval) from values ('- 1 second') t(v);
```

### What changes were proposed in this pull request?
In the PR, I propose new function `stringToInterval()` in `IntervalUtils` for converting `UTF8String` to `CalendarInterval`. The function is used in casting a `STRING` column to an `INTERVAL` column.
### Why are the changes needed?
The proposed implementation is ~10 times faster. For example, parsing 9 interval units on JDK 8:
Before:
```
9 units w/ interval 14004 14125 116 0.1 14003.6 0.0X
9 units w/o interval 13785 14056 290 0.1 13784.9 0.0X
```
After:
```
9 units w/ interval 1343 1344 1 0.7 1343.0 0.3X
9 units w/o interval 1345 1349 8 0.7 1344.6 0.3X
```
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
- By new tests for `stringToInterval` in `IntervalUtilsSuite`
- By existing tests

### What changes were proposed in this pull request?
Added new benchmark `IntervalBenchmark` to measure performance of interval related functions. In the PR, I added benchmarks for casting strings to interval. In particular, interval strings with `interval` prefix and without it because there is special code for this da576a737c/common/unsafe/src/main/java/org/apache/spark/unsafe/types/CalendarInterval.java (L100-L103) . And also I added benchmarks for different number of units in interval strings, for example 1 unit is `interval 10 years`, 2 units w/o interval is `10 years 5 months`, and etc.
### Why are the changes needed?
- To find out current performance issues in casting to intervals
- The benchmark can be used while refactoring/re-implementing `CalendarInterval.fromString()` or `CalendarInterval.fromCaseInsensitiveString()`.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
By running the benchmark via the command:
```shell
SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.IntervalBenchmark"
```
