KVM: VMX: Use vcpu_get_perf_capabilities() to get guest-visible value
Use vcpu_get_perf_capabilities() when querying MSR_IA32_PERF_CAPABILITIES
from the guest's perspective, e.g. to update the vPMU and to determine
which MSRs exist. If userspace ignores MSR_IA32_PERF_CAPABILITIES but
clear X86_FEATURE_PDCM, the guest should see '0'.

Fixes: c59a1f106f5c ("KVM: x86/pmu: Add IA32_PEBS_ENABLE MSR emulation for extended PEBS")
