  D3D11: Restrict use of MAX_UINT element indexes.
  
  We need to block the app from using MAX_UINT on D3D11 because we can't
  disable primitive restart on this platform. Instead generate an
  INVALID_OPERATION error, which is spec-compliant in ES3 because the
  result is undefined behaviour. This is also compliant with WebGL which
  explicitly defines an error here.
