KVM: x86: Use static_call() for .vcpu_deliver_sipi_vector()
Define and use a static_call() for kvm_x86_ops.vcpu_deliver_sipi_vector(),
mostly so that the op is defined in kvm-x86-ops.h. This will allow using
KVM_X86_OP in vendor code to wire up the implementation. Any performance
gains eeked out by using static_call() is a happy bonus and not the
primary motiviation.
