[vectorIntrinsics] RFR: 8244490: [vector] Move Vector API micro benchmarks under test/micro [v6]

[Marcus G K Williams]

> Vector API micro benchmarks are currently located under test/jdk/jdk/incubator/vector/benchmark which makes them rather as "dead" code without possibility to built and run.
> 
> The proper location for micro benchmarks is actually test/micro/ directory.
> It would be nice to move Vector API benchmarks there so they can be built automatically as part 'test-image' make target.
> Once they are built they can be run as
>  make run-test TEST=micro:BENCHMARK_TEST_NAME
