sched/numa: Implement NUMA node level wake_affine()
Since select_idle_sibling() can place a task anywhere on a socket,
comparing loads between individual CPU cores makes no real sense
for deciding whether to do an affine wakeup across sockets, either.
Instead, compare the load between the sockets in a similar way the
load balancer and the numa balancing code do.
