Georg Lehmann 7bb3f93fa9 radv: use nir_opt_clip_cull_const
This reduces the fixed function hardware bottleneck in vertex shading
heavy sections with d3d9 DXVK.

DXVK always declares 6 clip distances, and with
https://github.com/doitsujin/dxvk/pull/4508
it writes 0 for disabled clip planes.

But while working on this, I also discovered that other games also write
constant clip/cull distances:
