  Move the index range cache to gl::Buffer.
  
  Because we want to move all validation to the API layer, we need to
  move the index validation to the API layer. This means exposing the
  index cache to the validation layer.
  
  In the future we will probably want a way to skip index validation
  when it's not necessary, or the chosen back-end handles index
  validation on its own.
