tools headers UAPI: Sync drm/i915_drm.h with the kernel sources

To pick the change in:

  a0e047156cde ("drm/i915/gem: Make context persistence optional")
  9cd20ef7803c ("drm/i915/perf: allow holding preemption on filtered ctx")
  7831e9a965ea ("drm/i915/perf: Allow dynamic reconfiguration of the OA stream")
  4f6ccc74a85c ("drm/i915: add support for perf configuration queries")
  b8d49f28aa03 ("drm/i915/perf: introduce a versioning of the i915-perf uapi")
  601734f7aabd ("drm/i915/tgl: s/ss/eu fuse reading support")

That don't result in any changes in tooling, just silences this perf
