Subject: [EXTERNAL] [PATCH] Update perf auto profile script

- Fix gen_autofdo_event: The download URL for the Intel Perfmon Event
  list has changed, as well as the JSON format.
  Also it now uses pattern matching to match CPUs. Update the script to support all of this.
- Regenerate gcc-auto-profile with the latest published Intel model
  numbers, so it works with recent systems.
- So far it's still broken on hybrid systems
