Generate the resource file at configure time for Windows
Summary: Rather than using a pair of always out of date targets to regenerate the file every single time you build. Visual Studio is smart enough to detect the change to the files linked to by the resource, so let it do what it's good at, and make it so I can start hhvm with debugging after having just built it, without having to tell it I don't want to rebuild the resource files again -_-...
