drm/xe/tuning: Apply "Disable NULL query for Anyhit Shader" to Xe2

Extend the "Disable NULL query for Anyhit Shader" tuning to Xe2
(graphics version 2000+) platforms, in addition to Xe3.

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.
