lockup_detector: Adapt CONFIG_PERF_EVENT_NMI to other archs
CONFIG_PERF_EVENT_NMI is something that need to be enabled from the
arch. This is fine on x86 as PERF_EVENTS is builtin but if other
archs select it, they will need to handle the PERF_EVENTS dependency.
Instead, handle the dependency in the generic layer:
- archs need to tell what they support through HAVE_PERF_EVENTS_NMI
- Enable magically PERF_EVENTS_NMI if we have PERF_EVENTS and
HAVE_PERF_EVENTS_NMI.
