Stepan Ulyanin db01d87942 Add symlinkat, renameatx_np, and unlinkat system call wrappers (#3505) 
Adds three new system call wrappers for the `symlinkat`, `renameatx_np`,
and `unlinkat` system calls.

### Motivation:

Related to https://github.com/apple/swift-nio/issues/3403 and
https://github.com/apple/swift-nio/pull/3470. This PR adds syscall
wrappers needed to atomically overwrite existing files or symlinks at
the destination during copy operations. On Linux, atomic overwrites
require a "copy to temp file, then rename" strategy. We use the `*at`
family of syscalls (which operate relative to directory file
descriptors) to avoid TOCTOU race conditions.

### Modifications:

1. Adds three system call wrappers for the `symlinkat`, `renameatx_np`,
and `unlinkat` system calls.
2. Adds related tests
3. Updates the `FileSystemError` for `symlink` and `unlink` to take in
the system call name to allow for the `*at` names to be passed.

George Barnett a18bddb0ac Add back NIOFileSystem (#3380) 
Motivation:

We accidentally removed the 'NIOFileSystem' module from the
'_NIOFileSystem' product in the last release.

Modifications:

- Rename 'NIOFileSystem' and 'NIOFileSystemFoundationCompat' to 'NIOFS'
  and 'NIOFSFoundationCompat'
- Add back 'NIOFileSystem' which re-exports '_NIOFileSystem' (there was
  no publicly available 'NIOFileSystemFoundationCompat' module to
  remove, only '_NIOFileSystemFoundationCompat').

Result:

Fewer breaks
