perf/x86/intel: Process arch-PEBS records or record fragments

A significant difference with adaptive PEBS is that arch-PEBS record
supports fragments which means an arch-PEBS record could be split into
several independent fragments which have its own arch-PEBS header in
each fragment.

This patch defines architectural PEBS record layout structures and add
helpers to process arch-PEBS records or fragments. Only legacy PEBS
groups like basic, GPR, XMM and LBR groups are supported in this patch,
the new added YMM/ZMM/OPMASK vector registers capturing would be
supported in the future.
