WGL: support reset notifications via GL_ARB_robustness
Handling context losses is unavoidable with ANGLE. Introduce
some level of support for desktop GL too by making it possible
to opt in via a new flag.
Support is added for Windows (WGL, opengl32) only for now.
In case of Windows with ANGLE setting the flag is not necessary,
context losses will be reported regardless.
