Fix sluggish AI/camera eye movement (#28327)

* Fix sluggish AI eye movement

Fixes #28326

With the AI eye refactor, a `Moved()` callback was implicitly added to
each call to `set_loc` on a camera eye. As camera eyes are completely
invisible and do not directly interact with the game world, this extra
processing isn't necessary. Removing it also removed the noted
sluggishness.

* Re-adds Moved() call to set_loc, adds parameters

The Moved() call removed in the previous commit was not actually
completely unnecessary, or newly added. Rather, new parameters were
added that were not accounted form namely `momentum_change`. This commit
re-adds parent proc call to set_loc for camera eyes, and adds the
correct parameter values to Moved() in `/atom/movable/proc/set_loc`.
