Currently when a boosted task is scheduled we use prefer_idle to try and get it to an idle core. Once it's scheduled, there is a possibility we can schedule a non-boosted task on the same core where the boosted task is running on. This change aims to mitigate that possibility by checking if the core we're targeting has a boosted task and if so, use the next best idle core instead.
