Add support for bidirectional chargers to Wallbox integration (#74313)

Browse source 
* Add support for the Quasar bidirectional charger to the Wallbox integration, including ability to control charger while discharging, set a negative charge rate and monitor discharged amount

* Make code more generic in order to support other bidirectional models in the future

* Updates to files to comply with HA formatting rules

* Change const file to fix black check failure

* Remove unnecessay loop in number entity
