Add BW salt chlorinator device config (#5279)

* Add BW salt chlorinator device config

* Fix BW salt chlorinator fault bitmap sensor and tidy up

* Disable unreported BW chlorinator diagnostics by default

* Fix hidden optional BW chlorinator diagnostics

* Address review feedback and refine entity definitions

* Rename entity and add icon for water temperature sensor

- avoid names starting with numbers
