Fix internal temperature reading on ESP32 (#1391)

The previous macro used SENS_SAR_MEAS_WAIT2_REG to identify if we have the reading capability was not working, so replacing it by a fresh one NO_INT_TEMP_READING, defined as a negation due to the fact that most of the ESP32 supports internal temperature reading.
