sched: Factor out load calculation code from sched/core.c --> sched/proc.c
This large chunk of load calculation code can be easily divorced
from the main core.c scheduler file, with only a couple
prototypes and externs added to a kernel/sched header.
Some recent commits expanded the code and the documentation of
it, making it large enough to warrant separation. For example,
see:
556061b, "sched/nohz: Fix rq->cpu_load[] calculations"
5aaa0b7, "sched/nohz: Fix rq->cpu_load calculations some more"
5167e8d, "sched/nohz: Rewrite and fix load-avg computation -- again"
More importantly, it helps reduce the size of the main
sched/core.c by yet another significant amount (~600 lines).
