Expands "genderless" to all species, adds body-type option, removes some gender checks

What Does This PR Do

Continues https://github.com/ParadiseSS13/Paradise/pull/23469, and fundamentally revives the changes made in https://github.com/ParadiseSS13/Paradise/pull/16007.

Expands the "genderless" option to work across all species, beyond the few that already supported it. If you select this option, you will be referred to by most checks as they/them. On that note, this PR also adds a body-type option, between masculine and feminine, which allows you to change your base body sprite. This means that you can have a feminine body with male pronouns, or a masculine bodytype with plural pronouns.

This PR also does away with some checks based on gender, or associates them with bodytype instead of gender. I've made facial hair and all hairstyles accessible to both bodytypes, although undergarments are still limited per bodytype owing to sprite differences.

Why It's Good For The Game

This provides players with a lot more flexibility and control over how they might want to design their characters with appearance, how they present themselves, and how the game refers to them. This is a fantasy space simulator in the 2500s, at which point people probably do have a lot of control over their body.

Genderless species are also nothing new, with vox already having the option to be genderless, male, or female. On top of that, skrell have already been seemingly able to use both male and female hairstyles, which really begs into question why we don't have this for everyone.

Lastly, Paradise is kind of lagging behind its peers in supporting more advanced and inclusive customization options such as this. There are a fair amount of people in the SS13 community who have complicated relationships with gender, and it's a positive change to allow people to create the characters that they want to create. Even /tg/station, with its past reputation, has beaten us to the punch in this regard. It's about time for us to catch up.
