radeonsi: pass alpha_ref value to PS in the user sgpr
Currently it's hardcoded in the shader, so every change requires
compilation of the shader variant, killing the performance
in Serious Sam 3 and probably other apps.
This patch passes alpha_ref in the user sgpr and removes it from
the shader key.
