perf(climate): Heuristic Action and fix heating

[gtgt]

This feature calculates HVAC Action (from HVACMode and target/current temperatures) if the device is unable to do it.
Useful when you operate real device, like air-vales, heater, cooler, etc.

The upstream code contained some unnecessary lines and worked only with heating mode (as anything other climate stuff).

1. However the CURRENT_* constants were converted to HVACMode, instead of HVACAction, so this should be corrected.
2. The code is also updated to support Fan/Dry/HeatCool modes.

I think heuristic requires current and target temp to process other wise the logic will break and rise an error not? can you check this cleaned and has temps check

        if self._config.get(CONF_HEURISTIC_ACTION) and (
            self._target_temperature and self._current_temperature
        ):
            precision_target_diff = self._target_temperature - self._precision
            precision_current_diff = self._current_temperature + self._precision

            if self._hvac_mode == HVACMode.HEAT:
                if self._current_temperature < precision_target_diff:
                    self._hvac_action = HVACAction.HEATING
                if precision_current_diff > self._target_temperature:
                    self._hvac_action = HVACAction.IDLE
            if self._hvac_mode == HVACMode.COOL:
                if self._current_temperature > precision_target_diff:
                    self._hvac_action = HVACAction.COOLING
                if precision_current_diff < self._target_temperature:
                    self._hvac_action = HVACAction.IDLE
            if self._hvac_mode == HVACMode.HEAT_COOL:
                if self._current_temperature < precision_target_diff:
                    self._hvac_action = HVACAction.HEATING
                if self._current_temperature == precision_target_diff:
                    self._hvac_action = HVACAction.IDLE
                if precision_current_diff > self._target_temperature:
                    self._hvac_action = HVACAction.COOLING
            if self._hvac_mode == HVACMode.DRY:
                self._hvac_action = HVACAction.DRYING
            if self._hvac_mode == HVACMode.FAN_ONLY:
                self._hvac_action = HVACAction.FAN
            return self._hvac_action

I have a heater device switch to heating mode when self._current_temperature < self._target_temperature - self._precision_target, not self._target_temperature - self._precision. It also has a weekly circulation programming mode which has self._hvac_mode == HVACMode.AUTO
