BLI_kdopbvh: Use distance for BLI_bvhtree_ray_cast_all

Pass distance argument so its possible to limit the range we get all hits from.

Other changes:

- Use boundbox test before calling callback, avoids redundant calls.
- Remove meaningless return value.
- Add doc string, explaining purpose of this function.
