virt: rework kvm with hyperv enlightenment checks a bit

Let's avoid extending the virtualization with an "alias" entry that has
the same string assigned as another.

The only reason this was done was to make the patch small that added a
second CPUID vendor string for kvm to the vm_table[] array. Let's
instead rework the array to use struct elements that match up strings
with ids. Given the array was previously mostly sparse this should be a
general improvement.

Fixes: #22950
Follow-up for: #22945
