Localization support for any prototypes

[ficcialfaint]

About the PR

The PR adds ability to turn any prototype into localized prototype that supports localization in fluent file with custom prefix as entities do with ent- prefix.

How does it work?

There is now a new ILocalizedPrototype interface. You simply implement it in your prototype and add:

• SetName -- the default name you set in the prototype, in YAML files
• SetDesc -- same as SetName but for descriptions
• Name -- the localized name
• Description -- the localized description
• CustomLocalizationPrefix - the prefix that will be used in .ftl files. For example, entities use ent- prefix: ent-BaseItem = base item
  Then you have to set Name's and Description's getters to ILocalizationManager.GetPrototypeData<YourPrototype>(ID).Description / .Name.

Here is a small example for a localized prototype:

[Prototype("construction")]
public sealed class ConstructionPrototype : IPrototype, ILocalizedPrototype, ISerializationHooks
{
    private ILocalizationManager _loc = default!;

    [DataField("name")]
    public string? SetName { get; private set; }

    [DataField("description")]
    public string? SetDesc { get; private set; }

    [ViewVariables]
    public string Name => _loc.GetPrototypeData<ConstructionPrototype>(ID).Name;

    [ViewVariables]
    public string Description => _loc.GetPrototypeData<ConstructionPrototype>(ID).Desc;

    public string CustomLocalizationPrefix { get; private set; } = "cnt"; // e.g. cnt-BaseCraft = cool name

    void ISerializationHooks.AfterDeserialization()
    {
        _loc = IoCManager.Resolve<ILocalizationManager>();
    }
}

The given example is bad because it uses ISerializationHooks which are obsolete.
The localized strings should just get resolved once after prototypes have been (re)loaded, which would also mean you could just get rid of the caching dictionary.

[ElectroJr]

This doesn't recursively iterate up through a prototypes parents, this is just the direct parent list

try cast

[ElectroJr]

I might be wrong, but I don't think the data-field attributes do anything on interfaces?
I'm also not sure about whether VV works on interfaces.

[ElectroJr]

Also, these should have documentation comments

[ficcialfaint]

I just noticed the review, I'll see what I can do, thanks

[ElectroJr]

Needs to be per-prototype
NVM see my earlier comment, just remove it altogether.

[ElectroJr]

This should enumerate over kinds and only flush the cache for prototypes that actually changed.
Also FlushPrototypeCache() is broken, its just a copy paste of FlushEntityCache()
NVM see my earlier comment, just remove it altogether.

This is probably too old to merge anymore. Close?
