Camera: Add new set video format/dataspace command 

This allows the video encoding subsystem inform the camera what format
and dataspace should be used for metadata-mode buffers.

This is necessary to allow software encoders and other generic
consumers that cannot interpret
HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED buffers.
