Add data coordinator to incomfort integration (#118816)

* Add data coordinator to incomfort integration

* Remove unused code and redundant comment, move entity class

* Use freezer

* Cleanup snapshot

* Use entry.runtime_data

* Use freezer, use mock_config_entry

* Use tick

* Use ConfigEntryError while we do not yet support a re-auth flow, update tests

* Use tick with async_fire_time_changed
