vc4: Set the primitive list format at the start of rendering.

The other driver does this manually before calling into each tile, but we
can just let it get binned into the tiles (saving repeated kernel
validation on the packet).

Fixes simulator assertion failures on polygon-mode and non-auto texwrap.
