rcu/context_tracking: Move dynticks counter to context tracking
In order to prepare for merging RCU dynticks counter into the context
tracking state, move the rcu_data's dynticks field to the context
tracking structure. It will later be mixed within the context tracking
state itself.
[ paulmck: Move enum ctx_state into global scope. ]
