`System.runFinalization` marked as deprecated for removal

[lampajr]

Currently we are using System.runFinalization as part of the initial, enforced, garbage collection execution. See

Hyperfoil/core/src/main/java/io/hyperfoil/core/impl/SimulationRunner.java

Lines 525 to 535 in 7f3850b

	private void runSystemGC() {
	long actualGCRun = System.currentTimeMillis();
	// Run the GC twice and force finalization before every GC run
	System.runFinalization();
	System.gc();
	System.runFinalization();
	System.gc();
	log.info("GC execution took {} ms", (System.currentTimeMillis() - actualGCRun));
	}

Since version 18 the method was marked as deprecate for removal with:

Finalization has been deprecated for removal. See Object.finalize for background information and details about migration options.
When running in a JVM in which finalization has been disabled or removed, no objects will be pending finalization, so this method does nothing

We should probably start thinking if that is really needed and if so, how to migrate that.
