  Support primitive restart in RendererGL.
  
  Store index ranges in a new struct that tracks how many real indices were
  seen.  Update index caching to key on primitive restart being enabled and
  update index counting functions to skip primitive restart indicies when
  needed.
  
  Passes dEQP-GLES3.functional.primitive_restart.*
