KVM: selftests: Add timing_info bit support in vmx_pmu_caps_test

A new bit PERF_CAPABILITIES[17] called "PEBS_TIMING_INFO" bit is added
to indicated if PEBS supports to record timing information in a new
"Retried Latency" field.

Since KVM requires user can only set host consistent PEBS capabilities,
otherwise the PERF_CAPABILITIES setting would fail, add pebs_timing_info
into the "immutable_caps" to block host inconsistent PEBS configuration
and cause errors.

Opportunistically drop the anythread_deprecated bit.  It isn't and likely
never was a PERF_CAPABILITIES flag, the test's definition snuck in when
the union was copy+pasted from the kernel's definition.
