KVM: x86: make several APIC virtualization callbacks optional

Browse source

All their invocations are conditional on vcpu->arch.apicv_active,
meaning that they need not be implemented by vendor code: even
though at the moment both vendors implement APIC virtualization,
all of them can be optional.  In fact SVM does not need many of
them, and their implementation can be deleted now.
