Update the slice boost dynamically, as a function of the amount of CPUs in the system and the amount of tasks currently waiting to be dispatched: as the amount of waiting tasks in the task_pool increases, reduce the slice boost. This adjustment ensures that the scheduler adheres more closely to a pure vruntime-based policy as the amount of tasks contending the available CPUs increases and it allows to sustain stress tests that are spawning a massive amount of tasks.
