x86/pmu: Enable PEBS on fixed counters iff baseline PEBS is support

Enabling PEBS for fixed counters is only allowed if "Extended PEBS" is
supported, and unfortunately "Extended PEBS" is bundled with a pile of
other PEBS features under the "Baseline" umbrella.  KVM emulates this
correctly and disallows enabling PEBS on fixed counters if the vCPU
doesn't have Baseline PEBS support.
