The `BVHCacheType bvh_cache_type` parameter defines specific `BVHTrees` that cannot be customized. So it doesn't make sense to pass this value to any `*bvhtree_from_[...]_ex` function as the `BVHTrees` created in these cases are custom and cannot be saved in the cache. This also resulted in a nice cleanup in the code. Differential Revision: https://developer.blender.org/D14479
