Fix for AFS Mastodon: Items

[ghost]

Summary

SUMMARY: Bugfixes "Fix Mastadon armor and mutagen"

Purpose of change

#37660 introduced an armor set with the same name as their base variant, and the targeted mutagen is the wrong category.

Describe the solution

1.Move to correct file, change names. Delete old file.
2. Change names to add "XL" for the fingered gloves/boots/vest, Uplifted(leaving room open for future Uplifted mutation lines), or Killophant for the gloves(since they're stated to be made for them).
3.Put the names in the str/str_pl, if applicable.
4. Correct category of mastodon mutagen.

Describe alternatives you've considered

None.

Testing

Debugged in all items(profession has normal SWAT armor, fix in next PR).
Spawned in mutagen, game crashes when injecting/drinking(also in that PR).
