tree-wide: Introduce netif feature and use it This gets rid of a long list of boards with network interfaces and instead let's boards (or MCUs with peripheral network interfaces) provide the netif feature. The apps that before used the long list are not depending on the feature instead (in case of the default example, this is an optional dependency).
