sched: Generalize sleep inside spinlock detection

The sleeping inside spinlock detection is actually used
for more general sleeping inside atomic sections
debugging: preemption disabled, rcu read side critical
sections, interrupts, interrupt disabled, etc...

Change the name of the config and its help section to
reflect its more general role.
