Add DumpWithoutCrashing to debug renderer hangs

This CL is adding DumpWithoutCrashing to collect dumps of a suspected
root cause of renderer hangs.

We suspect the issue is related to WaitableEvent::TimedWaitImpl(...) which will infinite loop if WaitForSingleObject(...) is returning one
of the unhandled results. The goal of this CL is to collect minidumps
to validate the current hypothesis of an infinite loop.

This is currently hanging at the start of the HangWatcher when
trying to create the first simple thread. We expect to replace these
hangs by clean process shutdown.

Unfortunately, the cause of these error code is still a mystery.
