docs: update trademark disclaimer

It's a *long* time since SGI was the copyright holder for the OpenGL
trademark. And we implement more APIs by now, so let's update the
disclaimer to instead redirect to the Khronos licensing page for
details.

While we're at it, soften the language on legal status as a formal
implementation, as we currently have conformant drivers for most of the
APIs by now. But refer to the Khronos website for details, as
conformance status for drivers are subject to change.
