Use Singleton LifeCycle State

All entry points are for reconciliation are within batching strategies.

Since we don't have any batching strategies with synchronous updates,
there can't be more than one life-cycle method on the stack at any given
time.

Therefore, it's safe to move the composite life cycle flag to a singleton.
This saves us some memory management.

I think that we can get rid of these life cycle states completely in the
future.
