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. Bug: 13222807 Change-Id: I01090dc4dce11f075f7d3cd86daca5ecf3d9e995
