rcu: rename PREEMPT_AUTO to PREEMPT_LAZY

Browse source

Replace mentions of PREEMPT_AUTO with PREEMPT_LAZY.

Also, since PREMPT_LAZY implies PREEMPTION, we can reduce the
TASKS_RCU selection criteria from this:

  NEED_TASKS_RCU && (PREEMPTION || PREEMPT_AUTO)

to this:

  NEED_TASKS_RCU && PREEMPTION
