maxwell_to_gl: Implement MirrorOnceClampOGL using GL_MIRROR_CLAMP_EXT 

Like MirrorOnceBorder, this requires the GL_EXT_texture_mirror_clamp extension. This extension is unfortunately not available on Intel's drivers (both Windows proprietary and Linux Mesa). Use GL_MIRROR_CLAMP_TO_EDGE as a fallback if the extension is unavailable.
