  Implement robust initialization for image texture
  
  This change fixes a bug that the image texture initialization time is not
  correct. It happens when we use compute shader to write data to an
  uninitialized texture, then use readPixels to read the result which
  results that texture initialization falls behind image store and
  covers the real result.
  
  Bug: angleproject:2766
