perf/x86/intel: Parse CPUID archPerfmonExt leaves for non-hybrid CPUs
CPUID archPerfmonExt (0x23) leaves are supported to enumerate CPU
level's PMU capabilities on non-hybrid processors as well.
This patch supports to parse archPerfmonExt leaves on non-hybrid
processors. Architectural PEBS leverages archPerfmonExt sub-leaves 0x4
and 0x5 to enumerate the PEBS capabilities as well. This patch is a
precursor of the subsequent arch-PEBS enabling patches.
