wined3d: Add the ability to duplicate GL pixel shaders.

Some stateblock parameters have to be compiled into the GL pixel shader code, like lines for pixelformat fixups. This leads to problems when applications switch those settings, requiring a recompilation of the shader. This patch enables wined3d to have multiple GL shaders for a D3D shader(pixel shaders only so far) to handle this more efficiently.
