[insteon] set device offline if it doesn't exist in the plm/hub database (#12904)

* [insteon] set device offline if it doesn't exist in the plm/hub database
* [insteon] use a flag to indicate if a device is linked or not
* [insteon] set config to @NonNullByDefault({}) instead of @Nullable
* [insteon] cleanup
