25de091753 intel/nir: switch ray query state tracking to local variables uint16_t 
We should be able to use uint8_t but there appears to be a backend
bug.

Q2RTX shader compute shader improvement with ray queries :

0cf22f9af3 nir: Make rq_load committed src an index 
committed has to be a constant so there is no need to have a src and
depend on constant folding to remove the i2b.

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.

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.
