Adds support for building multiple BVH types in order to support using both CPU and OptiX devices for rendering simultaneously. Primitive packing for Embree and OptiX is now standalone, so it only needs to be run once and can be shared between the two. Additionally, BVH building was made a device call, so that each device backend can decide how to perform the building. The multi-device for instance creates a special multi-BVH that holds references to several sub-BVHs, one for each sub-device.
