  CL: Add some event/memory helper functions
  
  Add the following helper functions on the CL frontend
    - check for user event
    - check for CL image/buffer types
  
  And on the VK backend
    - For CLBufferVk/CLImageVk much of the state is encoded in the
      front-end object. Add utility functions to get handle to them.
    - check for user event dependency in commandqueue
