General maintenance for hand held camera (#95295)

## About The Pull Request
- Merged a lot of procs into procs `attempt_picture()` and
`interact_with_atom()` reducing proc overhead
- Taking pictures will now always use the cameras internal
`picture_size_x` & `picture_size_y`. It no longer accepts variable sizes
as parameters
- All camera operations are asynchronous and respects checks on if the
target can be captured on camera or not.
- A bunch of other code rearrangement that makes readability easier
- Fixes the following camera bugs. They fall under the same category
  - Fixes #95286
  - Fixes #95256

## Changelog
