perf/x86/amd/core: Add generic branch record interfaces
AMD processors that are capable of recording branches support either Branch Sampling (BRS) or Last Branch Record (LBR). In preparation for adding Last Branch Record Extension Version 2 (LbrExtV2) support, introduce new static calls which act as gateways to call into the feature-dependent functions based on what is available on the processor.
