Split peripheral-related logic into its own component

This has several advantages:

- `camera` no longer needs to define public functions for each
peripheral type.
- Peripheral-related is now no longer tighly coupled to human_player,
so peripheral logic can be reused elsewhere e.g.: on menus.
- Makes camera_update_touch consistent compared to equivalent functions,
since now `pan` has now been moved to `camera` (as it should be).
