Extended macro to accept flag indicating if given backend must be initialized and enabled when log subsystem starts. Typically, simple backends will have autostart flag set. More complex may require explicit enabling (e.g. shell over BLE can only be enabled when BLE connection is established). Signed-off-by: Krzysztof Chruscinski <krzysztof.chruscinski@nordicsemi.no>
