Climate - setpoint validation is missing mode context

[PeteRager]

The problem

The setpoint validation code in climate introduced in PR #118649 will improperly reject setpoints when a new hvac_mode is specified. For example, if the system is in heat mode and a setpoint is issued that changes the mode to cool. The setpoint may be validated against the acceptable range for heat mode; not for cool mode.

This is because the min and max temps reported in climate integration may be mode dependent. Here is an example from the honeywell integration:

core/homeassistant/components/honeywell/climate.py

Lines 242 to 248 in 74ba887

	@property
	def min_temp(self) -> float:
	"""Return the minimum temperature."""
	if self.hvac_mode == HVACMode.COOL:
	return self._device.raw_ui_data["CoolLowerSetptLimit"]
	if self.hvac_mode == HVACMode.HEAT:
	return self._device.raw_ui_data["HeatLowerSetptLimit"]
