Allow per-sensor unit conversion on BMW sensors (#110272)

* Update BMW sensors to use device_class

* Test adjustments

* Trigger CI

* Remove unneeded cast

* Set suggested_display_precision to 0

* Rebase for climate_status

* Change charging_status to ENUM device class

* Add test for Enum translations

* Pin Enum sensor values

* Use snapshot_platform helper

* Remove translation tests

* Formatting

* Remove comment

* Use const.STATE_UNKOWN

* Fix typo

* Update strings

* Loop through Enum sensors

* Revert enum sensor changes
