patch file

The attached patch adds some missing bits for full ARB_robustness compatibility,
specifically support for glGetGraphicsResetStatus() via WGL_ARB_create_context_robustness and GLX_ARB_create_context_robustness.

This builds upon patch [https://bugzilla.libsdl.org/show_bug.cgi?id=3643] and adds the WGL version.
I have removed support for NV_robustness_video_memory_purge from that patch because the extension states "This extension will have a limited lifespan" and I figured that adding an SDL API for a temporary NV-only extension isn't worth it.
I've also renamed the new enum values a bit to be more consistent.

Test program

A test program for the patch. On a recent GL 4.5 compatible setup + patched SDL it should print "GL context is fully robust".
