Raw fixes part 5
Cherry-picked from crop_rec_4k.
There are some more, but they depend on raw_capture_info. Will add another series after merging that.
For testing, it's probably best to confirm each issue in unified, then check whether it was fixed in this branch.
TODO:
- exact height for cameras with focus pixels (IIRC there are some issues with MLVFS)
- port the mlv_lite changes to mlv_rec if desired
