Add helpful text for Windows exceptions like Unix

On Unix if a process exits with a signal we'll print out which signal as
well as a small description of what happened, and this applies the same
logic to Windows. A few exit statuses are elaborated to their human
readable names (like `STATUS_ACCESS_VIOLATION`) to help for quick
debugging.
