perf evsel: Add is_pmu_core inorder to interpret own_cpus

The behaviour of handling cpu maps varies for core and other PMUs. For
core PMUs the cpu map lists all valid CPUs, whereas for other PMUs the
map is the default CPU. Add a flag in the evsel to indicate if a PMU
is core to help with later interpreting of the cpu maps and populate
it when the evsel is created during parsing. When propagating cpu
maps, core PMUs should intersect the cpu map of the PMU with the user
requested one.
