838bbdcf2e intel/nir/rt: store ray query state in scratch 
Initially I tried to store ray query state in the RT scratch space but
got the offset wrong. In the end putting this in the scratch surface
makes more sense, especially for non RT stages.

Initially the level is world (top level), then it's whatever level the
potential hit is.

f843bec7de intel/nir/rt: spill/fill the entire ray query data 
We need the traversal stack to saved/restored along with mem hits.
Total spill/fill is 256bytes.

We can potentially optimize this but we have to be very careful about
what state the query is in.
