feat: Adds cliloc support and fixes valuestringbuilder ctor (#1013)

- [X] Adds cliloc support using the following API:
```cs
public static class Localization
{
    string GetText(int number);
    string GetText(int number, string lang);
    string Format(int number, params object[] args);
    string Format(int number, string lang, params object[] args);

    string Format(int number, $"{arg1}{arg2}{arg3}");
    string Format(int number, lang, $"{arg1}{arg2}{arg3}");

    bool TryGetLocalization(int number, out LocalizationEntry entry);
    bool TryGetLocalization(int number, string lang, out LocalizationEntry entry);
}

public class LocalizationEntry
{
    string Language { get; }
    string Number { get; }
    string Text { get; }
    string?[] TextSlices { get; } // Used for string building
    string StringFormatter { get; }

    string Format(params object[] args);
    string Format($"{arg1}{arg2}{arg3}");
}
```

- [X] Fixes a bug with ValueStringBuilder and default initialization size
- [X] Optimizes ValueStringBuilder to use `ISpanFormattable`
- [X] Adds `Append<T>(T value);` support ValueStringBuilder
- [X] Adds `Append($"");` string interpolation support to ValueStringBuider
