This allows for extra output passes that encode automatic object and material masks for the entire scene. It is an implementation of the Cryptomatte standard as introduced by Psyop. A good future extension would be to add a manifest to the export and to do plenty of testing to ensure that it is fully compatible with other renderers and compositing programs that use Cryptomatte. Internally, it adds the ability for Cycles to have several passes of the same type that are distinguished by their name. Differential Revision: https://developer.blender.org/D3538
