Important changes to the NIOFileSystem module

The NIOFileSystem module has been renamed _NIOFileSystem to make it more
obvious that it isn't yet stable API.

The existing NIOFileSystem module currently re-exports _NIOFileSystem and will
be removed in the next minor release. You should update your imports accordingly
to avoid being broken by the next release.

• Add a helper for setting or cascading optional promises (#2697)
• Underscore the NIOFileSystem module (#2683, #2689)

• Add cancellation to NIOThreadPool's async runIfActive (#2679)
• Handle 'atomically' created files more gracefully when detached (#2682)
• Remove DispatchGroup and replace with condvar (#2687)
• Use NIOThreadPool in NIOFileSystem (#2692)
