Subject: [PATCH] refactor: migrate print_symbol to map-level raw: :content

lutaml-model deprecates attribute-level raw: true in favor of
declaring rawness on the XML mapping (raw: :content), which is
where it semantically belongs. Behavior verified unchanged:
parsed print_symbol values and XML round-trip output are
byte-identical for the full UCUM fixture (336 entities).
