RFR: 8350614: [JMH] jdk.incubator.vector.VectorCommutativeOperSharingBenchmark fails

[SendaoYan]

Hi all,

The newly added JMH test jdk.incubator.vector.VectorCommutativeOperSharingBenchmark run fails "java.lang.NoClassDefFoundError: jdk/incubator/vector/Vector".

The `@Fork(jvmArgsPrepend = ..)` in microbenchmarks should replaced as `@Fork(jvmArgs = ..)` after [JDK-8343345](https://bugs.openjdk.org/browse/JDK-8343345). Change has been verified locally, test-fix only, no risk.
