[Intel-xe] [PATCH v4 2/2] drm/xe: add gt tuning for indirect state

[Matt Atwood]

Force indirect state sampler data to only be in the dynamic state pool,
which is more convienent for the UMD. Behavior change mirrors similar
change for i915 in commit 16fc9c08f0ec ("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)
