  Vulkan: refactor CommandGraphResource
  
  Merged back RecordableGraphResource into CommandGraphResource.  Queries
  didn't really need to be a resource, as they always inserted separate
  single-command nodes in the graph.  The CommandGraph class is augmented
  with a few functions that generate such nodes.
  
  This is in preparation for debug markers, as they too require such
  nodes.
