  Make invalid extension directive a CHROMEOS warning
  
  This change allows extension directive after ESSL1.0 non-preprocessor tokens on CHROMEOS.
  CHROMEOS kiosks have a video player that violates this spec requirement so just flagging
  as a warning to prevent failed video playback.
  
  Added ANGLE_PLATFORM_CHROMEOS define to build config in order to only make this a warning
  on CHROMEOS. Split the ESSL1 & ESSL3 cases back out as ESSL3 had always been an error
  on all platforms in the past and so want to keep it that way.
