ray: cleanup ray_camera_frame_t fragments

Previously every fb_fragment_t (and thus thread) was constructing
its own ray_camera_frame_t view into the scene, duplicating some
work.

Instead introduce ray_camera_fragment_t to encapsulate the truly
per-fragment state and make ray_scene_render_fragment() operate
on just this stuff with a reference to a shared
ray_camera_frame_t prepared once per-frame.

Some minor ray_camera.c cleanups sneak in as well (prefer multiply
instead of divide, whitespace cleanups...)
