fix(json-ld): use a Skolem IRI instead of blank nodes

[soyuka]

Implements https://www.w3.org/TR/rdf11-concepts/Overview.html#section-skolemization instead of the previous blank nodes.

This patch also gives the ability to disable such @id using something like:

    #[ApiProperty(
        types: ['http://schema.org/MonetaryAmount'],
        iri: false
    )]
    public MonetaryAmount $totalPrice;

A note on this diff: usually ApiProperty was supposed to be backward compatible but this was reverted and we forgot to remove some of the portable code.
