This is one of the stages in the new element pipeline. It's a simple one, just a prefix sum of a couple counts, and some of it will probably get merged with a downstream stage, but we'll do it separately for now for convenience. This patch also contains an update to Vulkan tools 1.2.198, which accounts for the large diff of translated shaders.
