wined3d: Add a more formal framework for driver quirks. 

This allows better defining of driver desc fixups without adding extra if
lines for each card.

For starters, there's a fixup for the advertised GLSL constants in ATI cards.
fglrx advertises 512 GLSL uniforms instead of the supported 1024(means 128
instead of 256 vec4's). This bug was confirmed by ATI.
