AMD Last Branch Record Extension Version 2 (LbrExtV2) provides branch
speculation information and the perf UAPI is extended to provide this in a
generic manner. Update the tools headers and perf tool to be able to show
this additional information.

The LbrExtV2 enablement and UAPI changes can be found at:
