RFR: 8298596: vmTestbase/nsk/sysdict/vm/stress/chain/chain008/chain008.java fails with "NoClassDefFoundError: Could not initialize class java.util.concurrent.ThreadLocalRandom"

[Coleen Phillimore]

Moved the MethodHandle initialization out of the eatMemory function into the static initializer, so the eatMemory function doesn't get an unexpected OOM while loading the ThreadLocal class.
Tested 100x with ZGC with and without debug.
