0025234: Implementing LBVH builder

Performs fast BVH construction using LBVH building approach. Algorithm uses spatial Morton codes to reduce the BVH construction problem to a sorting problem (radix sort -- O(N) complexity). This Linear Bounding Volume Hierarchy (LBVH) builder produces BVH trees of lower quality compared to SAH-based BVH builders but it is over an order of magnitude faster (up to 4M triangles per second).
