encoding/protojson: use synthetic @type field for Any messages

In order for the synthetic @type field to potentially get reordered,
we implement insertion of that synthetic field by adding it
as a synthetic field that Range may iterate over.

This change sets up this code to more readily support a
hypothetical serialization mode for canonical serialization.
