vfio: selftests: Introduce struct iommu

Browse source

Introduce struct iommu, which logically represents either a VFIO
container or an iommufd IOAS, depending on which IOMMU mode is used by
the test.

This will be used in a subsequent commit to allow devices to be added to
the same container/iommufd.
