This will come in handy when we want to lower gl_CullDistance into
gl_CullDistanceMESA.
[airlied: drop separate APIs for clip/cull - just use single API
to call both passes.]
v3: reexamine my sanity, this was pretty broken, the new code
creates one copy of gl_ClipDistanceMESA, as the clip distance
varying and lowers everything into that in two passes, one for clips
one for culls.
v4: rework using the passes in clip/cull sizes, instead of the
array sizes.

This just renames the file in anticipation of adding cull lowering,
and renames the internals.
