Serve two purposes: 1. refcounting of vulkan handles with associated destruction. When combined with the trash list, the user can ensure destruction at the correct time according to the vulkan rules. 2. avoids polluting our API with 32-bit vs 64-bit integer/pointers differences as exposed through the vulkan API. on 32-bit, vulkan non-dispatchable handles are 64-bit integers and on 64-bit, they are pointers.
