kho: remove finalize state and clients
Eliminate the `kho_finalize()` function and its associated state from the
KHO subsystem. The transition to a radix tree for memory tracking makes
the explicit "finalize" state and its serialization step obsolete.
Remove the `kho_finalize()` and `kho_finalized()` APIs and their stub
implementations. Update KHO client code and the debugfs interface to no
longer call or depend on the `kho_finalize()` mechanism.
Complete the move towards a stateless KHO, simplifying the overall design
by removing unnecessary state management.
