docs/fs/ntfs: add mount options to support Windows native symbolic links

Introduce the "symlink=<value>" and the "native_symlink=<value>" mount
options to configure the creation behavior of symbolic links and support
creating Windows native symbolic links (reparse points with the
IO_REPARSE_TAG_SYMLINK tag).
