Benjamin WoodruffandGitHub 59160c612d Turbopack: Store watcher batch state with bitflags instead of 4 different sets (#96114) ...

Previously we we had 5 total `FxHashSet`s in `BatchedInvalidations`. Now
we've got one `FxHashMap` and one `FxHashSet`. There was potential
overlap in paths represented in all of these sets.

The old implementation was suboptimal for two reasons:
- We ended up cloning and storing `PathBuf` more times. (Note: there's a
good future opportunity for an arena here too)
- If a path was in both `path` and `path_and_children`, we'd later try
to invalidate paths associated with that twice. This will be a no-op as
we have a lock on the invalidator map and the duplicated path has
already removed from the invalidator map, but it makes us do extra map
lookups that aren't needed.

This still keeps around a separate set for `new_paths` so that we can
more efficiently iterate over them. It's possible it could benefit from
being a flag in the same set, but it's less obvious.
