libcamera: Add a SensorSensitivity property
The SensorSensitivity property is a scaling factor that describes how sensitive
the selected sensor mode is compared to other readout modes of the same sensor.
For example, a binned mode might have twice the sensitivity of the full
resolution mode, meaning you would get double the signal level for the same
exposure and gains.
