KVM: VMX: Smush x2APIC MSR bitmap adjustments into single function
Consolidate all of the dynamic MSR bitmap adjustments into vmx_update_msr_bitmap_x2apic(), and rename the mode tracker to reflect that it is x2APIC specific. If KVM gains more cases of dynamic MSR pass-through, odds are very good that those new cases will be better off with their own logic, e.g. see Intel PT MSRs and MSR_IA32_SPEC_CTRL. Attempting to handle all updates in a common helper did more harm than good, as KVM ended up collecting a large number of useless "updates".
