Test COMGLB_FAST_RUNDOWN on Windows 10

[jogerh]

Test how COMGLB_FAST_RUNDOWN affects time to call FinalRelease on server created objects in the Client address space after a server crash.

See branch https://github.com/jogerh/UnstructuredCom/tree/GarbageCollectionDemo

https://github.com/jogerh/UnstructuredCom/tree/GarbageCollectionDemo now shows a dialog after 5-15 minutes saying that Frame::FinalRelease was called on Windows 7. This demonstrates the delayed cleanup of COM objects after server crash.

To test on Windows 10, COMGLB_FAST_RUNDOWN is set on client side. It would be interesting to test if this affects the rundown time on Windows 10. If not, does it help enabling it on Player side?

I've now tested the branch, and the COMGLB_FAST_RUNDOWN flag seem to consistently reduce the delay before the Frame::FinalRelease dialog is shown from 5-6min to 10-11sec on my Win10 computer. This is still a while, but regardless a significant improvement.
