Description

We need to add a visitor to allow handling of the various pub variations.
pub(restricted) is interesting as it has a direct effect on surrounding modules: You can specify that a parent module, but not its parents, is allowed to view a certain item publicly

mod a {
  struct AStruct {
    inner: BStruct,
  }

  mod b {
    pub(in crate::a) struct BStruct;
  }
}

So we need to figure out a way to affect an HIR node's parents properly

Research direction

Start by locating the visitor that handles the various pub forms and the HIR representation of parent relationships. Use the pub(in crate::a) example as a reference; done means restricted visibility affects the specified parent module without granting access to its parents.
