RFR: 8265153: add time based test for ThreadMXBean.getThreadInfo() and ThreadInfo.getLockOwnerName()

[Daniel D.Daugherty]

The synopsis pretty much says it all. There's a more detailed history in the RFE itself.

Currently running the new test thru Mach5 Tier[1-7].
I've run the test thru several 12 hour runs on my MBP13 and
on my Linux-X64 server.
