rcu: Update trace.txt documentation to reflect recent changes
o Remove the CONFIG_PREEMPT_RCU documentation since this
config option has now been removed.
o Change the now-incorrect references to "rcu" labels to
instead be "rcu_sched".
o Add notes stating that CONFIG_TREE_PREEMPT_RCU kernels will
have additional "rcu_preempt" output.
o Note the new "oqlen" field in the rcuhier output (for
RCU callbacks orphaned by an offlined CPU).
