Add support for serializing identifiers in PersonJsonNormalizer and improve PersonIdentifier entity serialization.

- Extended `PersonJsonNormalizer` to include `identifiers` field normalization.
- Added `Serializer` annotations to `PersonIdentifier` and `PersonIdentifierDefinition` for enhanced serialization support.
- Updated `PersonIdentifier` and `PersonIdentifierDefinition` to define serialization groups and discriminator maps.
