Natalie Vock 6628ac8ad9 radv/rt: Avoid encoding infinities in box node coords
On Navi33, certain box sorting modes combined with infinity/-infinity in
the child AABBs cause image_bvh64_intersect_ray to return garbage node
pointers.

To avoid this, convert infinity to the maximum representable
floating-point value, which will still intersect with any non-inf ray.

Fixes consistent hangs in DOOM: The Dark Ages.
