This add support for rendering of the point cloud object in Blender, as a native geometry type in Cycles that is more memory and time efficient than instancing sphere meshes. This can be useful for rendering sand, water splashes, particles, motion graphics, etc. Points are currently always rendered as spheres, with backface culling. More shapes are likely to be added later, but this is the most important one and can be customized with shaders. For CPU rendering the Embree primitive is used, for GPU there is our own intersection code. Motion blur is suppored. Volumes inside points are not currently supported. Implemented with help from: * Kévin Dietrich: Alembic procedural integration * Patrick Mourse: OptiX integration * Josh Whelchel: update for cycles-x changes Ref T92573 Differential Revision: https://developer.blender.org/D9887
