feat(tvix/castore): add convenience `add` method to Directory r/7978
This adds `Directory::add` which is a convenience helper for adding
nodes into a `Directory` while preserving sorted order.

This implements `Ord` and `PartialOrd` for `FileNode`, `SymlinkNode`,
and `DirectoryNode` so `binary_search` can be used.
