context_tracking, rcu: Rename RCU_DYNTICKS_IDX into CT_RCU_WATCHING
The symbols relating to the CT_STATE part of context_tracking.state are now
all prefixed with CT_STATE.
The RCU dynticks counter part of that atomic variable still involves
symbols with different prefixes, align them all to be prefixed with
CT_RCU_WATCHING.
