  CL/Vulkan: Implement the buffer rect enqueues
  
  This change implements the buffer rect copy using a series of memcopies.
  The CL buffer rect doesn't map cleanly to the Vulkan copy buffer
  command due to the presence of pitches, and implementing as such will
  introduce more barriers in the command stream. For now we do process
  this command at call entry point.
