Metal backend does not support primtiive restart for point primtiives. Hence strip_restart_indices removes restart indices by swapping them to the end of the index buffer and reducing the length. An edge-case existed where all indices within the index buffer were restarts and no valid swap-index would be found, resulting in a buffer underflow.
