SF: Introduce LayerLifecycleManager

LayerLifecycleManager keeps track of layer lifecyle and state
changes. This breaks the existing model of using refbase and
LayerHandles to keep layer's alive. Instead, the
LayerLifecycleManager owns each layer and destroys them based
on the layer parent state and its handle state.

In addition, this class keeps track of requested layer state
changes, keeping track of change flags that make the data easier
to consume down the pipeline.

The code is not enabled.
