drm/xe/perf/uapi: Add perf_stream_paranoid sysctl

Browse source

Normally only superuser/root can access perf counter data. However,
superuser can set perf_stream_paranoid sysctl to 0 to allow non-privileged
users to also access perf data. perf_stream_paranoid is introduced at the
perf layer to allow different perf stream types to share this access
mechanism.
