Write is_unsigned flag into metadata for an annotation arguments

Instead of adding new kind of types, we'll use flag to disambiguate
 usual types from unsigned ones, this approach has two advantages:
 - less changes in the metadata format
 - it allows naturally extend format for unsigned arrays,
  which will be supported later
