Camera eyes have been lightly refactored (among other things...) (#87805)

## About The Pull Request

* A generic /mob/eye/camera type has been made, containing everything
needed to interface with a cameranet
* /mob/eye/ai_eye has been refactored into a generic /mob/eye/camera
instance
* Advanced cameras no longer inherit from AI eyes, splitting off
behaviour
* Camera code has been somewhat cleaned up
* Probably some more stuff I'm forgetting right now

## Changelog

🆑
code: made /proc/getviewsize() pure

refactor: mob/eye/ai_eye has been restructured, now inheriting from a
generic mob/eye/camera type
refactor: advanced cameras and their subtypes are now
mob/eye/camera/remote subtypes
code: the cameranet no longer expects the user to be an AI eye
code: remote camera eyes have had their initialization streamlined
code: remote cameras handle assigning and unassigning users by
themselves now
code: remote cameras now use weakrefs instead of hard referencing owners
and origins
code: also the sentient disease is_define was removed (we don't have
those anymore)
fix: AI eyes no longer assign real names to themselves, fixing their
orbit name
