Make whole types translatable

[gmiserez]

Currently, only fields can be made translatable.
If we use the same type, for example RiskClass, for several fields of our Schema, we need to put the Translate directive on every one of these fields:

public class Employee
{
        [Translate<RiskClass>(resourceKeyPrefix: "RiskClasses")]
        public RiskClass RiskClass{ get; }
}

public class ChemicalCompound
{
        [Translate<RiskClass>(resourceKeyPrefix: "RiskClasses")]
        public RiskClass RiskClass{ get; }
}

public class FinancialAsset
{
        [Translate<RiskClass>(resourceKeyPrefix: "RiskClasses")]
        public RiskClass RiskClass{ get; }
}

It would be neat to instead be able to translate and/or rewrite the type RiskClass globally, so that we only need to use the Translate Attribute once:

[Translate<RiskClass>(resourceKeyPrefix: "RiskClasses")]
public enum RiskClass
{
        Low,
        Medium,
        High,
}

This would then rewrite every field of type RiskClass to a TranslatedResourceOfRiskClass.
Support for the translatable and translated patterns would also be appreciated.
