wined3d: Use COLOROUT/DEPTHOUT for pixel shaders 2.0+. 

As previously mentioned, RASTOUT is invalid on pixel shaders.
On shaders 1.x, r0 is treated as the color output register:
http://www.gamedev.net/columns/hardcore/dxshader3/page2.asp
That's what we currently do in all cases, change it not to do so
for shaders >= 2.0. Support COLOROUT/DEPTHOUT instead.
