perf pmu: Count sys and cpuid JSON events separately

Sys events are eagerly loaded as each event has a compat option that may
mean the event is or isn't associated with the PMU.

These shouldn't be counted as loaded_json_events as that is used for
JSON events matching the CPUID that may or may not have been loaded. The
mismatch causes issues on ARM64 that uses sys events.

Fixes: e6ff1eed3584362d ("perf pmu: Lazily add JSON events")
