anv: Compile ray-tracing shaders

Browse Source 
This doesn't look too different from other compile functions we have in
anv_pipeline.c.  The primary difference is that ray-tracing pipelines
have this weird two-stage thing where you have "stages" which are
individual shaders and "groups" which are sort of mini pipelines that
are used to handle hits.  For any given ray intersection, only the hit
and intersection shaders from the same group get used together.  You
can't have an intersection shader from group A used with an any-hit from
group B.  This results in a weird two-step compile.
