perf/x86/rapl: Get quirk state from new probe framework
Getting the apply_quirk bool from new rapl_model_match array.
And because apply_quirk was the last remaining piece of data
in rapl_cpu_match, replacing it with rapl_model_match as device
table.
The switch to new perf_msr_probe detection API is done.
