Andreas Kling c9a35e104b AK: Add RefCountForwarder<T> 
This is a convenience template that implements reference count
forwarding. This means that an object forwards ref() and unref() to
another object.

We can use this when two ref-counted objects need to keep each other
alive. This situation poses two problems:

- Using 2x RefPtr would cause a ref cycle and leak both objects.
- Using 2x WeakPtr would allow one of them to be destroyed early.

With RefCountForwarder, only one of the objects has a ref count. The
object with the ref count points to the forwarding object by using a
non-counting smart pointer (OwnPtr or NonnullOwnPtr). Thus, both objects
are kept alive by the same ref count, and they can safely point to each
other without worrying about disjoint lifetimes.
