sched: Remove the sched heavy task frequency guidance feature
This has always been unused feature given its limitation of adding
phantom load to the system. Since there are no immediate plans of
using this and the fact that it adds unnecessary complications to
the new load fixup mechanism, remove this feature for now. It can
be revisited later in light of the new mechanism.
