[FEAT] _DEN Resomi markings

[kaminukurumi]

About the PR

Just a port of the entirety of Resomi markings into rebase. Using _DEN directory (_DEN/Entities & _DEN/Mobs) instead of being literally everywhere for future readability and easier reference.

Why / Balance

Helping out cut down at least a chunk of work.

Technical details

No proper filetree at the moment but I concur putting them into the _DEN directory is a much cleaner and easier to read idea than having to separate all of them again as initially because originally the Resomi content is spread everywhere.
This is also followed by Portfiend's guide.

Media

* Since the resomi species does NOT exist yet, the entirety of this visual is only added to humans for media documentation purposes to prove that it exists and is ready to be connected anytime.
