perf/x86/cstate: Use new probe function

Using perf_msr_probe function to probe for cstate events.

The functionality is the same, with one exception, that
perf_msr_probe checks for rdmsr to return value != 0 for
given MSR register.

Using the new attribute groups and adding the events via
pmu::attr_update.
