Retrieve any migration target implementation CPUs using the hypercall

One thing I am not sure here is how to handle the hypercall error.
Do we need to fail the Guest boot or just carry on without any
target implementation CPU support? At the moment it just carries on.

I vote for keeping the current behavior. This way the vmm could just
decide to never migrate this vm and if the vmm figures that the issue
is so severe that the vm should not continue it has the power to do so.
