Optimize OrderOnlyDeps computation using ResolvedTargetData caching

This is a follow-up to https://gn-review.googlesource.com/c/gn/+/22400
to address unresolved review comments.

- Add GetOrderOnlyDeps() to ResolvedTargetData to compute and cache order-only dependencies of targets in a bottom-up manner.
- Generalize this by making group() targets export the order-only dependencies of their direct dependents.
- Refactor NinjaBinaryTargetWriter::GetOrderOnlyDepsFromNonLinkableDeps to use this cached data and simplify duplicate elimination using UniqueVector<OutputFile>.
