RFR: 7903898: JMH: Unsafe deprecation warnings are printed in JDK 24

[Aleksey Shipilev]

This is printed for every benchmark running with JDK 24 now:


WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::objectFieldOffset has been called by org.openjdk.jmh.util.Utils (file:/Users/shipilev/Work/shipilev-jmh/jmh-samples/target/benchmarks.jar)
WARNING: Please consider reporting this to the maintainers of class org.openjdk.jmh.util.Utils
WARNING: sun.misc.Unsafe::objectFieldOffset will be removed in a future release


These have not failed for a long time, so we can just trust the padding works. This will also avoid running some of this checking code during benchmark execution, adding to benchmark accuracy.
