tests: Add ISM330DL temperature to multidriver comparison scenario.

[nedseb]

Context

The multidriver temperature comparison scenario (board_temperature_comparison.yaml, PR #100) currently reads temperature from 4 sensors: HTS221, WSEN-HIDS, WSEN-PADS, and LIS2MDL.

The ISM330DL (IMU) also has a built-in temperature sensor. Once PR #50 is merged and the ISM330DL driver is integrated, it should be added to the comparison scenario.

TODO

• Add ISM330DL temperature reading to board_temperature_comparison.yaml
• Add /remote/ism330dl to sys.path and drivers list
• Verify the ISM330DL temperature method name and call signature

Depends on

• PR ism330dl: Add ism330dl driver. #50 (ISM330DL driver)
• PR tests: Add multidriver temperature comparison scenario for calibration. #100 (multidriver temperature comparison)
