ThreadDump: Capture Access Denied exceptions

When doing a dump within a Control-C handler under Windows, dumping threads may result in an UnauthorizedAccessException "Access is denied" when capturing the native threads PriorityLevel, or "System.ComponentModel.Win32Exception (0x80004005): Access is denied" when capturing the user time, or total time.

If those exceptions occur, just abort the capture, but we still log what ever information was available up until the exception.

Issue: HELIOS-1350
