    aarch64: Use error_n for plural text [PR104897]
    
    Use error_n rather than error_at for “%d vectors”, so that
    translators can pick different translations based on the
    number (2 vs more than 2, etc.)

            (function_resolver::infer_vector_or_tuple_type): Use error_n
            for "%d vectors" messages.
