allMandatoryParameters and validationMethod = NONE don't work together

[xtaixe]

Hi. It seems that there is an incompatibility between allMandatoryParameters and validationMethod = NONE.

When having something like:

@Value.Immutable
@Value.Style(
        allMandatoryParameters = true,
        typeAbstract = "_*",
        typeImmutable = "*",
        validationMethod = NONE,
        defaults = @Value.Immutable(builder = false))
public interface _MyType {

    String property();

}

only a no-args factory method MyType.of() is created instead of the expected MyType.of(String property).

If I use allParameters instead of allMandatoryParameters or remove validationMethod = NONE everything works as expected.

yes, seems like something that can be fixed, thank you

I've reread ValidationMethod.NONE javadoc and it seems that it is making attributes non mandatory, and unfortunately enough users might rely on this behavior even if a little bit regrettable in a way it is named/documented. So "fixing" it is not an option.
I've introduced new ValidationMethod.MANDATORY_ONLY constant to still have non-nullable non-default attributes mandatory with the regular check for missing attributes, just omit null-check on value.
