  d3d11: Support rendering to GL_TEXTURE_2D target for YUV images
  
  YUV D3D11 texture plane EGLImages can be bound to TEXTURE_EXTERNAL_OES,
  but don't support rendering because ExternalImageSibling11::IsYUV()
  returns true. While it might appear that IsYUV() should return true for
  YUV D3D11 textures, the EGLImage siblings are actually for individual
  planes which are R/RG 8/16 and they can indeed be bound as render
  targets if we just return false for IsYUV().
  
  This CL makes IsYUV() return false and adds a test for rendering to
  YUV EGLImages.
