Cherrypick: Add Undergarments & "Censor Nudity" Toggle to Options (#33185)

[mnva0]

About the PR

This PR cherrypicks space-wizards/space-station-14#33185
This will undoubtedly conflict with #77 because I forgot I even had that open

Not all underwear markings might fit with all IPC torso markings but whatever
Resomi are excluded because they need special sprites or one hell of a displacement map. If even possible
Hydrakin would also require special sprites. Bottom undergarments technically fit them, but might look out-of-place without the possibility of top undergarments
I included normally-nonplayable-or-not-roundstart species because... why not? Non-zero chance they get made playable or somehow end up with underwear

There are some very minor problems:

• Reptilian legs don't exactly fit into bottom underwear. Digitigrade and whatnot. They already have unique sprites which won't be too hard to adjust, so I've kept their access to bottom undergarments
• Missing FTL entry at marking-UndergarmentBottomSatinReptilian-satin_reptilian (if I transcribed correctly). This is extremely trivial and only shows up in the color selection dropdown. I believe upstream tried fixing this before but I reverted the fix (on upstream) for breaking the marking names. May have to double up on entries or rewrite C# code to fix it
• You can kinda see the Binder marking (maybe more) through a greyshirt Feroxi a bit? It's like 2 pixels on each side. This probably doesn't matter
• There might be some weird layering issue with Harpy wings. I don't know. Maybe look into NF for a possible solution or something. Maybe DV. Not sure if this is even a problem or if I'm imagining it

By the way I had a HELL of a time getting this to work on the Git end. Tell me if something is off
I have taken an EXCEPTIONALLY LONG time to make this PR. My PRs do not get better in quality as I spend more time on them, they get worse

Why / Balance

This is a wholesome family-friendly server! Put some underwear on! \j
I understand making characters not totally nude will be a very controversial PR \j

At the very least me and one other person want underwear. Customization, plus people don't have to go completely nude. Some clothings are also kind of revealing so it's nice having another layer

Media

Requirements

• I have read relevant guidelines/documentation to this PR found on our devwiki.
• I have added media to this PR or it does not require an ingame showcase.
• I can confirm this PR contains either no AI-generated content, or AI-generated content that meets our guidelines.

How to test

1. Open character editor
2. Try out the species. You shouldn't find any FTL issues and the underwears should fit
3. Open the options and try out the new underwear-related accessibility option. It puts underwear on naked people

Changelog
🆑 SlamBamActionman, Minerva

• add: Top and bottom undergarments can now be found in the Markings tab of the character creator.
• add: The Accessibility tab of Options now has a Censor Nudity Toggle, which adds undergarments to all characters on your client. Undergarments selected in the character creator take priority.
• remove: The following species were not given undergarments due to sprite body shape reasons: Resomi, Hydrakin. Reptilian legs don't quite fit into bottom undergarments, but they have kept access to those markings.

Fix sprites for hydrakin, reptilians, resomi, and any other species with different-looking legs please

[TheRealMasterChief117]

Fine for now, but we'll need custom underwear sprites for the other species or working displacements
