tracker/pt: refactor camera info handling

- Pass `struct CamInfo' rather than several elements separately
- Reformat
- Return `struct CamInfo' together with the frame since then it's always valid
- Move the focal length formula into `struct CamInfo'
- Remove incorrect focal length formula rather than #if 0
- Pass some stuff by reference and not by pointer
