This sets the DIS_NULL_QUERY bit in RT_CTRL to disable null query for Anyhit shaders on both Xe2 and Xe3. This is a change in behavior that can regress a userspace not prepared for it. However it's not feasible to change dynamically the option per client or per exec queue via an opt-in flag. Mesa is already prepared for that and it got propagated to their stable versions. Even if it was possible, at this point adding a flag would mean mesa would also need to propagate such a flag to their stable versions, otherwise the previous fix would not be used.
