OpenGL interop

[Raniz85]

I need to access the OpenGL interop functions found in cuda_gl_interop.h. The documentation lists them under the Runtime API so they might fit inside the runtime crate.

It does use a few OpenGL types so a dependency on the gl crate is probably needed as well. I don't know how hard it is to add feature flags for different bindgens so maybe a cuda-gl-interop-sys crate is the better route.

Interop crates/features for D3D could probably be added at the same time in a similar manner.
