Remove many of the Hide properties

A follow-up to !3679 (merged), this attempts to make the items hidden by the petsuit better match what they were before.

I think there's a bug in CharacterAppearanceVisible, as it first looks at an asset's main Hide and then consults a typed asset's Hide property afterward, leading to being unable to have a type de-hide something that the asset hid. This means that the behavior that I expected (stuff in Item.Property overrides stuff in Item.Asset, which overrides stuff in Group in some cases).

A fix for that isn't that hard, but I definitely don't want to touch that function in the end of the beta. Also, if Nina or Ellie have an opinion on that, it'd be nice to hear it.
