Add new functions to ADS sensor integration (#125331)

* feat: Add new functions to ADS sensor integration

* fix: use constant for SensorDeviceClass, refactor entity initialisation.

* fix: add python typing.

* refactor: value conversion based on ADS_TYPE, and in the dedicated data fetching method.

* fix: removed unnecessary sensor types.

* refactor: optimised the usage of device classes and added state classes. removed unit of measurement

* fix: added unit of measurement to ADS sensor

* fix: addressing review suggestions.

* fix: address review suggestions.
