rsx: Shader pipeline fixes and improvements

Browse source 
- Do not set zfunc if alphakill is not enabled. This is because at the moment alphakill requires a different shader to be built

- use glsl loop-unroll friendly comparison; skip vertex input compare if either key requests it

- Minor tweaks to fp key generation
