iommu/virtio: Break out bypass identity support into a global static
To make way for a domain_alloc_paging conversion add the typical global
static IDENTITY domain. This supports VMMs that have a
VIRTIO_IOMMU_F_BYPASS_CONFIG config.
If the VMM does not have support then the domain_alloc path is still used,
which creates an IDENTITY domain out of a paging domain.
