  Vulkan: Reorganize helper classes.
  
  This renames ResourceVk to vk::CommandGraphResource, which should help
  clarify its usage. This also moves LineLoopHandler, ImageHelper, and
  the DynamicBuffer and DynamicCommandPool classes into a new vk_helpers
  module. This file contains helper classes that manage other resources.
  
  Also this makes DynamicBuffer and DynamicDescriptorPool no longer
  inherit from CommandGraphResource. In the future, only Impl objects
  will be allowed to be graph resources.
