  GL: Implement EXT_YUV_target
  
  Add test coverage of YUV format sampling as RGB or directly as YUV and
  rendering as YUV using layout(yuv).
  
  Initializing YUV AHardwareBuffers requires Android API 29 so ANGLE must
  be compiled with:
  android32_ndk_api_level = 29
  android64_ndk_api_level = 29
  
  The following tests can still run with Android API 26 because they don't
  need to initialize the buffer:
  ImageTestES3.ClearYUVAHB
  ImageTestES3.YUVValidation
