Closing in favor of #4723. I tried to keep them separate, but the fixes needed got way too intertwined. |

Description
This adds the necessary logic so that
@builtin(instance_index)works correctly wrt the base instance in direct draw calls.We currently don't even issue draw calls using the BaseInstance draw function of gl (we rebind the instance rate buffers), so indirect will be fun to pull off at a future time.
