  Add WGLWindow and WGL test configs.
  
  WGLWindow lets us use a Windows driver's bindings instead of ANGLE.
  This only works if the underlying driver supports OpenGL ES
  compatibility.
  
  Also adds the WGL headers, WGL XML, and a specialized WGL loader.
  
  Because of a small driver issue with NVIDIA I added a retry for the WGL
  Window initialization.
  
  Bug: angleproject:2995
