NanoVDB is a platform-independent sparse volume data structure that makes it possible to use OpenVDB volumes on the GPU. This patch uses it for volume rendering in Cycles, replacing the previous usage of dense 3D textures. Since it has a big impact on memory usage and performance and changes the OpenVDB branch used for the rest of Blender as well, this is not enabled by default yet, which will happen only after 2.82 was branched off. To enable it, build both dependencies and Blender itself with the "WITH_NANOVDB" CMake option. Reviewed By: brecht Differential Revision: https://developer.blender.org/D8794
