sched/core: add helpers for iowait handling

Adds helpers to inc/dec the runqueue iowait count, based on the task, and
use those in the spots where the count is manipulated.

Adds an rq_iowait() helper, to abstract out how the per-rq stats are read.

No functional changes in this patch, just in preparation for switching
the type of 'nr_iowait'.
