KVM: x86: Add APIC_LVTx() macro.
An APIC_LVTx macro is introduced to calcualte the APIC_LVTx register offset based on the index in the lapic_lvt_entry enum. Later patches will extend the APIC_LVTx macro to support the APIC_LVTCMCI register in order to implement Corrected Machine Check Interrupt signaling.
