  Vulkan: Refactor ImageViewHelper serials.
  
  Instead of storing a dictionary of serials to specific image views
  we now store a single 32-bit serial combined with subresource info.
  The serials combined with a subresource info (level/layer) gives a
  unique identifier for each ImageView in the ImageViewHelper for the
  descriptor set cache and the Framebuffer cache.
  
  Also moves ImageView serial allocation to initialization and release.
  This means we no longer need to use "getAssign" methods and instead
  we use a few init methods to ensure the serials stay allocated.
