Rust: adapt QL library to ra_ap 0.0.347 schema

Update hand-written library predicates for the 0.0.347 AST changes:
- FormatArgsArg.getArgName() -> getName() (the arg name is now a Name,
  carrying text, instead of the text-less FormatArgsArgName placeholder).
- Visibility.getPath()/hasPath() -> getVisibilityInner().getPath(); the
  path now hangs off an intermediate VisibilityInner node.
