nir: add lowering stage for user-clip-planes / clipdist
The vertex shader lowering adds calculation for CLIPDIST, if needed
(ie. user-clip-planes), and the frag shader lowering adds conditional
kills based on CLIPDIST value (which should be treated as a normal
interpolated varying by the driver).
Note that this won't quite do the right thing in the face of MSAA plus
user-clip-planes, since all the samples would be killed or not (rather
than potentially only a portion of them). But it's better than no UCP
support at all for drivers that don't have this in hw.
