[Port] StepTriggerGroup From WhiteDream (#929)

# Description

This is a port of
https://github.com/WWhiteDreamProject/wwdpublic/pull/53 from White
Dream. This PR improves the StepTriggerImmune component by making it
operate on a more granular Blacklist system, such that StepTriggerImmune
entities can further clarify via prototypes which kinds of floor traps
they are immune to, such as landmines/mousetraps, and not have blanket
immunity to everything. Because it turns out things like Lava and Soap
also were caught by the immunity, when really we just wanted Harpies &
Felinids to not trigger landmines.

> # Описание
> Необходимо настроить модификатор урона, чтобы IPC не получали урон от
осколков стекла.
>
> Иммунитет StepTriggerImmuneComponent доработан. Теперь имеются
несколько типов (types): Lava - тип тайла, наступив на который
появляется урон. Это собственно лава и LiquidPlasma Landmine - мины.
Chasm - дырка в карте, куда можно провалиться Mousetrap - Мышеловка
SlipTile - Все, что должно подскальзывать игроков, имеющее размер тайла
SlipEntity - Все, что должно подскальзывать игроков, имеющее развер
энтити. Разделено для баланса. Самые ловки могут игнорировать мелкие
предметы (энтити), т.е. уворачиваться от них. Но большие по площади вещи
(тайлы по типу разлитой воды, бананиума) просчитываются отдельно.

# Changelog

🆑 Hell_Cat
Feature: StepTriggerSystem has been improved with new StepTriggerGroups.
Additionally, the StepTriggerImmune component now allows declaring for
specific StepTriggerGroups for a given entity to be immune to. Some
examples may be, Felinids, Mice, and Harpies being unable to set off
Landmines.
