Configurable Perf metrics

The Perf metrics use the Linux kernel perf_event_open() system call to provide additional CPU related metrics available for Arm® MAP.

They can be used on any system supported by the Linux perf command (also called perf_event). These cannot be tracked on typical virtual machines.
