Vulkan.Utils.RefCounted

Lightweight reference counter that runs a release action when the count hits zero. Useful for keeping a Vulkan object alive across an unknown number of in-flight frames — bump the count when a frame starts using it, drop the count when the frame retires, and the object is destroyed promptly after the last frame finishes.
