The LifetimeCollectVisitor had a bug where it was not recording the binder of bate trait objects. This was uncovered in #114487, when I changed opaque type lowering to ICE if it encountered a captured fresh lifetime with no def-id to map back to: https://github.com/rust-lang/rust/pull/114487/files#diff-ad0c15bbde97a607d4758ec7eaf88248be5d6b8ae084dfc84127f81e3f7a9bb4R1585

Fixes #114664
