Create public function to convert virCPUDef data structure into
qemuMonitorCPUModelInfoPtr data structure.
There was no existing code to reuse to create this function
so this new virQEMUCapsCPUModelInfoFromCPUDef function was based on
reversing the action of the existing virQEMUCapsCPUModelInfoToCPUDef
function.
