sched: Avoid frequent task migration due to EA in lb
A new tunable exists that allow task migration to be throttled when the
scheduler tries to do task migrations due to Energy Awareness (EA). This
tunable is only taken into account when migrations occur in the tick
path. Extend the usage of the tunable to take into account the load
balancer (lb) path also.
In addition ensure that the start of task execution on a CPU is updated
correctly. If a task is preempted but still runnable on the same CPU the
start of execution should not be updated. Only update the start of
execution when a task wakes up after sleep or moves to a new CPU.
