Subject: 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.
