nir: Define system values for vc4's blending-lowering arguments.
In the GLSL-to-NIR conversion of VC4, I had a bit of trouble with what I
was calling the "state uniforms" that I was putting into the NIR fighting
with its other lowering passes. Instead of using magic uniform base
numbers in the backend, follow the lead of load_user_clip_plane and just
define system values for them.
v2: Fix unintended change to channel_num, drop unspecified const_index
value on blend_const_color_r_float.
