  Extend multiview perf tests to cover all extension code paths
  
  The ANGLE_multiview extension can be supported with three possible code
  paths - through view being selected in the vertex shader on D3D and
  OpenGL, and through the view being selected in the geometry shader on
  D3D only. This patch extends the multi-view performance tests to
  benchmark these three different code paths.
