bme280: Add support for BMP280 and BME680 sensors (#4040)

Browse Source 
This adds support for BMP280 and BME680 sensor ICs,
along with fixing calibration data readout for BME280.

Gas sensor readout for the BME680 is just the raw compensated value.
To get actual meaningful values, more research is needed.
