[libvirt] [PATCHv2 09/16] qemu: Introduce virQEMUCapsToVirtType
The function is needed to support multiple accelerators without
cluttering codebase by conditionals.
At the first glance that might cause an issue related to the ordering
capabilities being checked on a system with many accelerators but in the
current code base it should be just fine because
virQEMUCapsGetHostCPUData is not interested in the exact type of
accelarator.
