KVM: x86/pmu: Restrict GLOBAL_{CTRL,STATUS}, fixed PMCs, and PEBS to PMU v2+
Restrict support for GLOBAL_CTRL, GLOBAL_STATUS, fixed PMCs, and PEBS to
v2 or later vPMUs. The SDM explicitly states that GLOBAL_{CTRL,STATUS} and
fixed counters were introduced with PMU v2, and PEBS has hard dependencies
on fixed counters and the bitmap MSR layouts established by PMU v2.
