- New CuBQLRayTracer class with working create_surface_tree and basic ray queries - Updated plucker_ray_tri intersect to play nice with openmp target offload regions - Implemented new structs for cuBQL BVH objects with XDG data - Implemented mixed precision BVH traversal algorithm for cuBQL - Updated appropriate constants with new cuBQL specifics - Ensured cuBQL properly wired through to xdg public API

This is a branch where I was playing around with pre-computing normals in FP32 and storing them on mesh data objects transferred to device to avoid the cost of doing the FP64 cross product for each candidate primitive. I'll use this internal PR to document my efforts to measure performance and robustness of this.
Already initial testing has shown between a 6-7% increase in rays/sec whilst running my throughout benchmark but I need to ensure the robustness is still reasonable too.
