virtio_pci: move structure to a header
These are guest/host interfaces, so they belong in the header where e.g.
qemu will know to find them.
Note: we added a new structure as opposed to extending existing one
because someone might be relying on the size of the existing structure
staying unchanged. Add a warning to avoid using sizeof.
