[climate-1.0] Add RoundThermostat to evohome (#25141)

* initial commit

* improve enumeration of zone(s)

* remove unused self._config

* remove unused self._config 2

* remove unused self._id

* clean up device_state_attributes

* remove some pylint: disable=protected-access

* remove LOGGER.warn(

* refactor for RoundThermostat

* ready for review

* small tweak

* small tweak 2

* fix regression, tweak

* tidy up docstring

* simplify code
