Subject: [PATCH v4 37/38] KVM: Selftests: Support mediated vPMU for vmx_pmu_caps_test

From: Dapeng Mi <dapeng1.mi@...ux.intel.com>

Define KVM_ONE_VCPU_PMU_TEST_SUITE macro which calls
vm_create_with_one_vcpu_with_pmu() to create mediated vPMU enabled VM.

Then vmx_pmu_caps_test can supported mediated vPMU's validation.
