sched/doc: add a preemption model overview
The scheduler documentation describes the individual scheduling classes
and various tuning knobs, but there is nothing that describes the
preemption models themselves. The only place where they are documented
is the kernel-parameters entry for "preempt=", which explains the boot
time parameter but not the models it selects.
Add a short overview of the models, what separates them, which of them a
given kernel offers, and how a scheduling request is honoured under each.
