KVM: selftests: Check for APIC access virtualization support in said test
Not all CPUs that support VMX necessarily support the "virtualize APIC
accesses" secondary processor-based VM-execution control. For example,
some Zhaoxin CPUs lack this feature. Add a capability check before
running the test to properly skip on unsupported hardware instead of
failing.
Carve out the guts of kvm_cpu_has_ept() into a generic helper and use said
helper to provide kvm_cpu_has_vmx_apic_access_virt().
