iommufd/selftest: Add nested domain allocation for mock domain
Add nested domain support in the ->domain_alloc_user op with some proper
sanity checks. Then, add a domain_nested_ops for all nested domains and
split the get_md_pagetable helper into paging and nested helpers.
Also, add an iotlb as a testing property of a nested domain.
