st/nine: Avoid Constant upload when there is no change

It is very common for d3d9 apps to set again the constants
they need before every draw call, even if nothing changed.

Since we are mostly gpu bound, it is better to check
for change, and upload constants again (and thus use
gpu bandwith) only if the constants changed.
