cpu: Use virDomainCapsCPUModelsPtr in cpu driver APIs

Browse Source 
All APIs which expect a list of CPU models supported by hypervisors were
switched from char **models and int models to just accept a pointer to
virDomainCapsCPUModels object stored in domain capabilities. This avoids
the need to transform virDomainCapsCPUModelsPtr into a NULL-terminated
list of model names and also allows the various cpu driver APIs to
access additional details (such as its usability) about each CPU model.
