Add support for 16-bps (48-bpp) RGB output formats in the uapi headers.
These new formats are defined for the RGB and BGR ordering.

The corresponding change submitted to the linux-media and DRM mailing
lists can be found at:

https://lore.kernel.org/linux-media/20240502110503.38412-3-jacopo.mondi@ideasonboard.com/
and
https://lore.kernel.org/dri-devel/20240226132544.82817-1-jacopo.mondi@ideasonboard.com/

respectively.
