sched/fair: Use augmented rbtree instead of 2 rbtreessched/latency-nice
Use augmented rbtree to save a wakeup_vruntime for the latency sensitive
tasks in addition to the normal vruntime instead of using a dedicated
rbtree.
a wakeup_vruntime field is added on sched_entity that will be set at enqueue
to take into account the latency offset wheen needed.
A min_vruntime field is also added to the sched_entity for the augmented
function to keep track of the minimum wakeup_vruntime of the rb subtree of a
node.
