zink: move primitive-topology stuff into program

The primitive topology is a bit of an odd-ball, as it's the only
truly draw-call specific state that needs to be passed to the program to
get a pipeline.

So let's make this a bit more explict, by passing it separately. This
makes the flow of data a bit easier to wrap your head around.
