drm/i915/ats-m: Add thread execution tuning setting
On client DG2 platforms, optimal performance is achieved with the
hardware's default "age based" thread execution setting. However on
ATS-M, switching this to "round robin after dependencies" provides
better performance. We'll add a new "tuning" feature flag to the ATS-M
device info to enable/disable this setting.
