IBS events with exclude_{user,kernel} bits, as used for per-thread
recording when kernel samples are not allowed, are rejected on hardware
without the privilege filter, so per-thread 'perf mem record' fails on
AMD:
$ perf mem record -o /dev/null -- true
Failure to open event 'ibs_op/ldlat=0/u' on PMU 'ibs_op' which will be removed.
Kernel v6.14 added swfilt, a software privilege filter exposed as the
'swfilt' format term, making those events usable per-thread. Give the
ibs_op memory events extra tables with the term, selected in
perf_pmu__arch_init() when the PMU exposes it, keeping the names that
need system wide mode otherwise; the knowledge that IBS needs this
stays in the arch code.
