drm/xe/uapi: restrict system wide accounting

Browse source

Since this is considered an info leak (system wide accounting), rather
hide behind perfmon_capable().

v2:
  - Without perfmon_capable() it likely makes more sense to report as zero,
    instead of reporting as used == total size. This should give similar
    behaviour as i915 which rather tracks free instead of used.
