Add "sync_state" to KNX lights in yaml

Integration name

KNX

Describe the enhancement

It seems that the "sync_state" for a KNX light entity can only be set in the UI, but not in the YAML configuration. It would be nice if we could also set the "sync_state" in the YAML configuration.

Use cases

First, I would say it is an inconsistency between the UI and the YAML configuration. Also, the load on the bus system can be reduced since a sync is mainly needed at startup, since the KNX actor would report changes in the state anyway.

Anything else?
