Fix rustdoc infinitely recursing when an external crate reexports itself
Previously, rustdoc's LibEmbargoVisitor unconditionally visited the child modules of an external crate. If a module re-exported its parent via 'pub use super::*', rustdoc would re-walk the parent, leading to infinite recursion. This commit makes LibEmbargoVisitor store already visited modules in an FxHashSet, ensuring that each module is only walked once. Fixes #40936
