x86,fs/resctrl: Replace architecture event enabled checks
The resctrl file system now has complete knowledge of the status of every
event. So there is no need for per-event function calls to check.
Replace each of the resctrl_arch_is_{event}enabled() calls with
resctrl_is_mon_event_enabled(QOS_{EVENT}).
No functional change.
