Aaron Klotz c084ff85e4 Bug 1508468: Convert launcher process to use mozilla::Result for error propagation; r=mhowell
This patch does a couple of things:

* I added a new class, |WindowsError| to WinHeaderOnlyUtils. The idea here is
  to encapsulate as much of the Windows error gamut as possible into one class.
  Since Win32 errors and NTSTATUS codes may both be encoded as HRESULTs, I
  used the latter type to store the error. It also contains functions for
  converting between the various error code formats, as well as stringification
  via FormatMessage.

* I added |LauncherError| which also includes file and line number information,
  which I believe will be important for launcher process failure diagnostics.
  (Instantiation of LauncherErrors obviously must be done via macros to capture
  __FILE__ and __LINE__).

* I then converted all of the launcher process code (and its few depenencies) to
  utilize this new functionality via the new |LauncherResult| type.

* If we detect an error in one of the top-level launcher process functions, we
  pass it to |HandleLauncherError| for processing. This function currently just
  throws up a |MessageBox| like the previous code did, with the intention of
  enhancing that further in the future.
