Add readable state for tesla wall connector (#107909)

* Add readable state for tesla wall connector

* Add test

* Display raw sensor by default

* Use none instead of unknown

* Remove old state from tests

* Rename raw state to status code

* Test unknown

* Update homeassistant/components/tesla_wall_connector/strings.json
