The major functionality gain this provides is proper reference counting for a descriptor set. Overall this allows us to create descriptor sets when they are needed (or reused from a cache) without violating any of vulkan's object synchronisation requirements. As there are a fixed number of sets available in a pool, the number of descriptors in elements is currently hardcoded to 32. This can be extended in a future change to create pools on the fly if that limit is ever overrun.
