perf/x86: Remove unused PERF_PMU_CAP_HETEROGENEOUS_CPUS capability 

Since commit bd27568117 ("perf: Rewrite core context handling") the
relationship between perf_event_context and PMUs has changed so that
the error scenario that PERF_PMU_CAP_HETEROGENEOUS_CPUS originally
silenced no longer exists.

Remove the capability to avoid confusion that it actually influences
any perf core behavior. This change should be a no-op.
