libcamera: controls: Add sensor black levels reporting through metadata
The black levels will be used when saving RAW data in DNG containers. Four values are reported, one for each channel, in the order R, Gr, Gb and B. The values are reported as being out of a 16-bit pixel range (a fully saturated pixel would be 65535), so may need subsequent re-scaling, depending on use.
