  OpenCL: Replace error-return APIs to use angle::Result
  
  The motivation of converting existing CL APIs using
  "cl_int errorCode" to now use "angle::Result" is for better
  interop with internal ANGLE plumbing/abstractions.
  
  To facilitate this, we now make use of a TLS errorCode
  object that we set internally and read from entrypoint/stubs
  layer so that we can propagate back to user.
