Message : 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 Change-Id: Ie5148ece470dd03df33015f4919ad1fa79a859ec Reviewed-on: https://chromium-review.googlesource.com/c/1366021 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Yuly Novikov <ynovikov@chromium.org>
