  Vulkan: Use ResourceUse to track object lifetime.
  
  With the new resource tracking scheme the CommandGraph, tracking a
  "Context serial" aka "current" serial is no longer necessary for
  CommandGraphResources. Serial tracking has been moved to the shared
  ResourceUse struct that gets updated on a command submission. Thus
  we don't need to store the serial as a current separate piece of info
  in BufferHelper/ImageHelper.
  
  Will lead to further redesign for the multi-threading support for
  Vulkan.
