x86/cpufeatures: Add Architectural PerfMon Extension bit
CPUID.(EAX=07H, ECX=1):EAX[8] indicates whether the Architectural
PerfMon Extension leaf (CPUID leaf 23) is supported.
The "X86_FEATURE_..., word 12" is already mirrored from CPUID
"0x00000007:1 (EAX)". Add X86_FEATURE_ARCH_PERFMON_EXT under the
"word 12" section.
The new Architectural PerfMon Extension leaf (CPUID leaf 23) will be
supported in the perf_events subsystem later.
The feature will not appear in /proc/cpuinfo.
