This method gathers the list of devices supported by the hypervisor,
and intersects this list with the list of devices supported
by the OS, natively or using a driver (added with
gvir_designer_domain_add_driver()). The lists can be filtered if
needed.
This commit changes gvir_designer_domain_get_supported_disk_bus_types()
to make use of that new helper. This will slightly change its behaviour
as before this commit, it will consider any block devices from
GVirDesignerDomain::os, while after this commit, it will only
consider block devices from GVirDesignerDomain::os that are supported
by GVirDesignerDomain::platform.
This will cause a change for example for OSes that only list
virtio-block as a supported block device, such as Fedora as
described in libosinfo v0.2.6-9-g7a8deb4
