On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first move some pmu common code from vpmu_counter_access to lib/ which can be used by pmu_event_filter_test. Then implements the test itself.
