    [USERSRV] Hard-error improvements 3/7
    
    - Cache localized hard error message components: the status severity,
      the system process name and the unhandled exception debug strings.
    - Try not to fail too much. In particular, don't fail if a string could
      not be correctly captured in UserpCaptureStringParameters() (we then
      use a default empty string). The next aim is to make UserpFormatMessages()
      not failing at all.
    - Use RtlStringCbPrintf(Ex)W where possible so that one can use counted
      (and not NULL-terminated) UNICODE_STRINGs where possible. This allows
      using counted resource strings without having to allocate memory.
    - If available, prepend the window title of the application that
      triggered the hard error to the hard error message box caption.
