dts: arm: st: Add adc support of the temperature sensor on stm32

Add the support of the temperature sensor in the ADC device-tree node of
each stm32 where it is available.
- Check all the ADC of the stm32 mcus where the temp and VrefInt monitoring
is available (based on the Ref Man).
- Check that has-temp-channel; and has-vref-channel; in the corresponding
ADC node of the DTS of each stm32 mcu is correctly set.
- Verify the VTEMP/ VREFINT activation in the in adc_stm32.c for example).
-Add the die-temp node (based on the ref man/ datasheet).
