perf tools: Add cpu_map processor socket level functions
This patch adds: - cpu_map__get_socket: get socked id from cpu - cpu_map__build_socket_map: build socket map - cpu_map__socket: gets acutal socket from logical socket Those functions are used by uncore and processor socket-level aggregation modes.
