[libvirt] [PATCHv2 1/3] qemu_monitor_json: Populate CPUModelInfo struct from json
New function qemuMonitorJSONBuildCPUModelInfoFromJSON
created by extracting code from existing function qemuMonitorJSONGetCPUModelExpansion
to create a reusable function for extracting cpu model info from json.
Function qemuMonitorJSONGetCPUModelInfoFromJSON
returns qemuMonitorCPUModelInfoPtr on success and NULL on failure.
