  Add shader translator support for OVR_multiview
  
  The OVR_multiview and OVR_multiview2 extensions add gl_ViewID_OVR to
  shaders. gl_ViewID_OVR can be translated either as is in GLSL output
  or as a uniform by setting the SH_TRANSLATE_VIEWID_OVR_AS_UNIFORM
  compiler flag.
  
  If WebGL output is selected, the shaders will be validated according
  to proposed rules in the WEBGL_multiview spec.
