rsx: Implement QUAD_STRIP

Browse source 
- QUAD_STRIP evaluates to TRIANGLE_STRIP in memory. The memory layout is identical.
- The only difference between the two modes would be the primitive_ID but that doesnt matter on RSX
- Its worth noting that results will be different between the two modes if input vertices are non-coplanar for every set of N verts
