[SPARK-48021][ML][BUILD] Add `--add-modules=jdk.incubator.vector` to
`JavaModuleOptions`
### What changes were proposed in this pull request?
The pr aims to:
- add `--add-modules=jdk.incubator.vector` to `JavaModuleOptions`
- remove `jdk.incubator.foreign` and `-Dforeign.restricted=warn` from
`SparkBuild.scala`
### Why are the changes needed?
1.`jdk.incubator.vector`
First introduction: https://github.com/apache/spark/pull/30810
https://github.com/apache/spark/pull/30810/files#diff-6f545c33f2fcc975200bf208c900a600a593ce6b170180f81e2f93b3efb6cb3e

Why should we add `--add-modules=jdk.incubator.vector` to
`JavaModuleOptions`,
Because when we only add `--add-modules=jdk.incubator.vector` to
`SparkBuild.scala`, it will only take effect when compiling, as follows:
```
build/sbt "mllib-local/Test/runMain
org.apache.spark.ml.linalg.BLASBenchmark"
...
```
<img width="619" alt="image"
src="https://github.com/apache/spark/assets/15246973/54d5f55f-cefe-4126-b255-69488f8699a6";>
However, when we use `spark-submit`, it is as follows:
```
./bin/spark-submit --class org.apache.spark.ml.linalg.BLASBenchmark
/Users/panbingkun/Developer/spark/spark-community/mllib-local/target/scala-2.13/spark-mllib-local_2.13-4.0.0-SNAPSHOT-tests.jar
```

src="https://github.com/apache/spark/assets/15246973/8e02fa93-fef4-4cdc-96bd-908b3e9baea1";>
Obviously, `--add-modules=jdk.incubator.vector` does not take effect in the
`Spark runtime`, so I propose adding `--add-modules=jdk.incubator.vector` to
the `JavaModuleOptions`(`Spark runtime options`) so that we can improve
`performance` by using `hardware-accelerated BLAS operations` by default.
After this patch(add `--add-modules=jdk.incubator.vector` to the
`JavaModuleOptions`), as follows:
<img width="1399" alt="image"
src="https://github.com/apache/spark/assets/15246973/da7aa494-0d3c-4c60-9991-e7cd29a1cec5";>
2.`jdk.incubator.foreign` and `-Dforeign.restricted=warn`
A.First introduction: https://github.com/apache/spark/pull/32253
https://github.com/apache/spark/pull/32253/files#diff-6f545c33f2fcc975200bf208c900a600a593ce6b170180f81e2f93b3efb6cb3e
<img width="1041" alt="image"
src="https://github.com/apache/spark/assets/15246973/3f526019-c389-4e60-ab2a-7777f8e99cfb";>
Use `dev.ludovic.netlib:blas:1.3.2`, the class `ForeignLinkerBLAS` uses
`jdk.incubator.foreign.*` in this version, so we need to add
`jdk.incubator.foreign` and `-Dforeign.restricted=warn` to `SparkBuild.scala`
https://github.com/apache/spark/pull/32253/files#diff-9c5fb3d1b7e3b0f54bc5c4182965c4fe1f9023d449017cece3005d3f90e8e4d8
<img width="497" alt="image"
src="https://github.com/apache/spark/assets/15246973/4fd35e96-0da2-4456-a3f6-6b57ad2e9b64";>
https://github.com/luhenry/netlib/blob/v1.3.2/blas/src/main/java/dev/ludovic/netlib/blas/ForeignLinkerBLAS.java#L36
<img width="743" alt="image"
src="https://github.com/apache/spark/assets/15246973/4b7e3bd1-4650-4c7d-bdb4-c1761d48d478";>
However, with the iterative development of `dev.ludovic.netlib`,
`ForeignLinkerBLAS` has experienced one `major` change, as following:
https://github.com/luhenry/netlib/commit/48e923c3e5e84560139eb25b3c9df9873c05e41d
<img width="452" alt="image"
src="https://github.com/apache/spark/assets/15246973/7ba30b19-00c7-4cc4-bea7-a6ab4b326ad8";>
From now on (V3.0.0), `jdk.incubator.foreign.*` will not be used in
`dev.ludovic.netlib`
Currently, Spark has used the `dev.ludovic.netlib` of version `v3.0.3`. In
this version, `ForeignLinkerBLAS` has be removed.
https://github.com/apache/spark/blob/master/pom.xml#L191
Double check (`jdk.incubator.foreign` cannot be found in the `netlib`
source code):
<img width="674" alt="image"
src="https://github.com/apache/spark/assets/15246973/5c6c6d73-6a5d-427a-9fb4-f626f02335ca";>
So we can completely remove options `jdk.incubator.foreign` and
`-Dforeign.restricted=warn`.
B.For JDK 21
(PS: This is to explain the historical reasons for the differences between
the current code logic and the initial ones)
(Just because `Spark` made changes to support `JDK 21`)
