drm/xe: add gt tuning for indirect state

which is more convienent for the UMD. Behavior change mirrors similar
change for i915 in commit 16fc9c08

 ("drm/i915: disable sampler
indirect state in bindless heap")

v2: split out per engine tuning into separate patch, commit message
(Lucas)
v3: rebase
v4: Change to match render only, g.ver 1200 to 1271 (MattR)
