[v1,0/3] KVM: selftests: aarch64: Introduce pmu_event_filter_test

Message

The test is inspired by the pmu_event_filter_test which implemented by x86. 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.
