virDomainXMLOption: Introduce virDomainABIStabilityDomain

Browse Source 
While checking for ABI stability, drivers might pose additional
checks that are not valid for general case. For instance, qemu
driver might check some memory backing attributes because of how
qemu works. But those attributes may work well in other drivers.
