Logging for morph snacks (#92301)

## About The Pull Request

This PR simply adds logging whenever a morph eats something (and where
it was at the time)

## Why It's Good For The Game

These are barely available to players in-game but if admins spawn them
or something it's quite hard to track what they were actually doing,
considering how disruptive they can potentially be

## Changelog
