Use ScopedObjectAccess in ThreadList::Dump
Prevent deadlocks if two different threads are calling Dump at the
same time:
Thread 1: Requests thread 2 to suspend
Thread 2: Requests thread 1 to suspend
Both threads are suspended and blocked on ScopedObjectAccess in
thread dumping.
Added to suspend all stress, reduced thread count to 4 temporarily
since this is the maximum number of simultaneous checkpoints.
