perf/amd/ibs: Advertise zen4_ibs_extensions as pmu capability attribute
PMU driver can advertise certain feature via capability attribute('caps'
sysfs directory) which can be consumed by userspace tools like perf. Add
zen4_ibs_extensions capability attribute for IBS pmus. This attribute
will be enabled when CPUID_Fn8000001B_EAX[11] is set.
With patch on Zen4:
$ ls /sys/bus/event_source/devices/ibs_op/caps
