Embed a @meta_type structure in NMMetaSettingInfoEditor and NMMetaPropertyInfo. This allows to make the NMMeta*Info instances themself to become generic and they can be passed around as generic NMMetaAbstractInfo types. For one, the embedded NMMetaType pointer can be used to determine of which type a NMMetaAbstractInfo instance is. On the other hand, the NMMetaType struct can be extended to be a VTable to provide generic access to the type. In the end, both NMMetaSettingInfoEditor and NMMetaPropertyInfo are conceptionally very similar: the describe a certain type and provide accessors. In nmcli we have yet another NMMetaAbstractInfo type: NmcOutputField will be modified to become another implementation of meta data (it already is, it just cannot be used interchangable with the other types). Also, embed the NMMetaSettingInfoEditor in the NMMetaPropertyInfo instance. This allows from a given NMMetaPropertyInfo to retrieve it's parent NMMetaSettingInfoEditor.
