Fixes Ice Slipping, Refactors noslip mechanics, Allows magboots to prevent slip slides (but not the slip itself) (#73948)

## About The Pull Request

Code changes: 

- Fixes #73946 , Ice Slipping not going forever as intended
- Detailed in the issue report. Ice slide slip was replaced from a stun
to a knockdown, but it relied on it being a stun to function. I replaced
it back with an immobilize and incapacitate, reduced to 1 second to
prevent cheese.

- Refactors noslip mechanics
- Changes noslip and noslip_ice from a clothing flag to a clothing
trait, as the trait already existed and was used by MODsuits. Also added
noslip_slide, which prevents all sliding from slips like lube.

- Refactors magboots
- Refactored and modernized magboot code. Mostly cleanup, like using
base icon state, updating appearance, etc.

- Fixes speed potioned magboots not maintaining the speed boost after a
toggle

- Adds a helper for adding or removing clothing traits from existing,
(potentially) worn items.

- `TRAIT_NEGATE_GRAVITY` now always updates gravity on signal, no longer
requiring a manual call after.

Balance change: 

- Magboots now prevent sliding on permafrost (outside icebox).  
   - This is mainly to give them more of a purpose on Icebox. 
- Magboot snow prevent sliding on ice (or lube). You will still slip. 
- Slipping over ice or lube will knock you down as before, but will not
send you across the room.

## Why It's Good For The Game

Magboots justification: 

This makes Magboots much less of a "noob trab" for engineers
fire-fighting in the Supermatter room. Most engineers believe themselves
to be completely save to the Supermatter's pull with magboots, however
"wet ice" will still send you flying into the crystal.

I think it is an inconsistency, seeing as it protects you from other
forms of forced movement like gravitational pulls. However making them
pure no-slip seemed a bit too far to me, so the knockdown still occurs.

## Changelog

🆑 Melbert
balance: Magboots will now protect you from sliding on ice. It will not
stop the slip, though.
fix: "Ice sliding" (from patches of permafrost ice) will now correctly
slide you until you reach a non-ice patch.
fix: Speed potioned magboots maintain their speed booster after toggling
them
refactor: Refactored magboots. 
refactor: Refactored noslip mechanics.
