AMD Last Branch Record Extension Version 2 (LbrExtV2) provides branch
speculation information and the perf UAPI is extended to provide this in
a generic way. Make perf tool show this additional information.

The UAPI changes can be found in commit 93315e46b000 ("perf/core: Add
speculation info to branch entries").

Previous versions can be found at:
v2: https://lore.kernel.org/all/cover.1664356751.git.sandipan.das@amd.com/
v1: https://lore.kernel.org/all/cover.1660217326.git.sandipan.das@amd.com/

Changes in v3:
- Drop tools-side UAPI changes as they have already been added by other
  commits.
- Rebase on top of latest perf/core.

Changes in v2:
- Drop msr-index.h related changes for now.
- Rebase on top of latest perf/core.
- Fix UAPI breakage introduced by the ARM64 BRBE changes to perf branch
  entry.

  perf session: Show branch speculation info in raw dump
