KVM: x86/pmu: Move handling PERF_GLOBAL_CTRL and friends to common x86
Move the handling of GLOBAL_CTRL, GLOBAL_STATUS, and GLOBAL_OVF_CTRL,
a.k.a. GLOBAL_STATUS_RESET, from Intel PMU code to generic x86 PMU code.
AMD PerfMonV2 defines three registers that have the same semantics as
Intel's variants, just with different names and indices. Conveniently,
since KVM virtualizes GLOBAL_CTRL on Intel only for PMU v2 and above, and
AMD's version shows up in v2, KVM can use common code for the existence
check as well.
