  CL/Vulkan: cl_khr_external_memory extension (pt.2)
  
    - Make this extension visible if Vulkan implementation support
      features supportsExternalMemoryFd and/or
      supportsExternalMemoryDmaBuf
    - Implemented APIs clEnqueueAcquireExternalMemObjectsKHR and
      clEnqueueReleaseExternalMemObjectsKHR
    - Updated clCreateBufferWithProperties to handle external memory
      file descriptor.
