Fix broken layer hiding on clothes with multiple equipment slots (#34080)

Fix broken layer hiding on clothes with multiple equipment slots (#34080)

* Fix broken layer hiding on clothes with multiple equipment slots

* Refactor ToggleVisualLayers, HideLayerClothingComponent, and ClothingComponent to allow more
precise layer hide behavior and more CPU efficient layer toggling.

* Adjust HumanoidAppearaceSystem to track which slots are hiding a given layer (e.g. gas mask and welding mask)
Add documentation
Change gas masks to use the new HideLayerClothingComponent structure as an example of its usage

* Fix the delayed snout bug

* Misc cleanup

* Make `bool permanent` implicit from SlotFlags

any non-permanent visibility toggle with `SlotFlags.None` isn't supported with how its set up. And similarly, the slot flags argument does nothing if permanent = true. So IMO it makes more sense to infer it from a nullable arg.

* Split into separate system

Too much pasta

* Remove (hopefully unnecessary) refresh

* Fisk mask networking

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* Keep old behaviour, use clearer names?

I'm just guessing at what this was meant to do

* english

* Separate slot name & flag

* dirty = true

* fix comment

* Improved SetLayerVisibility with dirtying logic suggested by @ElectroJr

* Only set mask toggled if DisableOnFold is true

* FoldableClothingSystem fixes

* fix bandana state

* Better comment
