JNI Local References could be found on the stack(first 8 of them) or from GC_VMThreadJNISlotIterator (vmThread->jniLocalReferences). need to update MM_ReferenceChainWalker::doVMThreadSlot() to report J9GC_ROOT_TYPE_JNI_LOCAL type for the case walkState->slotType = J9_STACKWALK_SLOT_TYPE_JNI_LOCAL.

relate: #18378 and #17712

if (isHeapObject(slotValue) && !_heap->objectIsInGap(slotValue)) {
doSlot(slotPtr, J9GC_ROOT_TYPE_STACK_SLOT, -1, (J9Object *)walkState);
if (J9_STACKWALK_SLOT_TYPE_JNI_LOCAL == ((J9StackWalkState *)walkState)->slotType) {
doSlot(slotPtr, J9GC_ROOT_TYPE_JNI_LOCAL, -1, (J9Object *)walkState);;
