nir: Apply fragment color clamping to gl_FragData[] as well.
From the ARB_color_buffer_float spec:
35. Should the clamping of fragment shader output gl_FragData[n]
be controlled by the fragment color clamp.
RESOLVED: Since the destination of the FragData is a color
buffer, the fragment color clamp control should apply.
Fixes arb_color_buffer_float-mrt mixed on v3d.
