[PATCH v4 09/44] perf vendor events intel: Add tigerlake metric constraints

[Ian Rogers]

Previously these constraints were disabled as they contained topdown
events. Since:
https://lore.kernel.org/all/20230312021543.3060328-9-irogers@xxxxxxxxxx/
the topdown events are correctly grouped even if no group exists.

This change was created by PR:
https://github.com/intel/perfmon/pull/71

Signed-off-by: Ian Rogers <irogers@xxxxxxxxxx>
