ray: add module context ray_context_t
Before I can clean up the ray_scene_t._prepared kludge I need a place to keep state from frame prepare to render, enter context. Future commits will migrate the _prepared stuff into a separate ray_render_t which is constructed on prepare then acted on in fragment render. Then spatial acceleration structures may be added, constructed at prepare phase and shared across the concurrent rendering.
