Thermostat remove deprecated config (#3643)

* Raise errors for all the now deprecated options

* Fix CONF_DEFAULT_PRESET detection

* Stop attempting to set the non-existent normal_config

* Add support for default presets

* Fix correct detection of Two Point temperature mode

* Fix lint issues

* Fix tests

* Generate correct yaml for equivalent configurations

* Remove debug code

* Only set default preset if the thermostat does not have state to restore

* Add restore_default_preset_on_boot option
If set to True then the default_preset will be applied on every boot. If False (Default) state will be restored from memory as per prior versions

* Apply lint suggestions

* Switch from restore_default_preset_on_boot to an enum for startup_behavior
This gives better self-documentation as well as the option for extending to other options down the track

* Lint fixes

* Rename startup_behavior to on_boot_restore_from
This removes any issues with different English locales

* Fix comparable_preset yaml output alignment

* Add dump of on_boot_restore_from setting
