Improve usability of the Vogen Json Converter

[bnaya-corp]

Describe the feature

Please add a static property for each converter.
It will keep the code cleaner when using it:

For this one:

[ValueObject<string>(Conversions.SystemTextJson | Conversions.TypeConverter)] 
public readonly partial record struct Email
{
}

• Current

var serilizationOptions = new JsonSerializerOptions();
serilizationOptions.Converters.Add(
            new Email.EmailSystemTextJsonConverter());

• Desired

var serilizationOptions = new JsonSerializerOptions();
serilizationOptions.Converters.Add(
            Email.EmailSystemTextJsonConverter);

i.e. having a static property of a singleton converter

Thanks for the feedback @bnaya-payoneer .

Did you know that Vogen generates a VogenTypesFactory that you can provide to STJ to resolve the converters?

Also, it is planned to generate these converter classes outside of the type itself. They still need direct access to the private _value field, but Vogen, in other converters, uses System.Runtime.CompilerServices.UnsafeAccessor to access this so as to avoid reflection.
