Scheduler: Add protections for Yield bombing
In case of redundant yields, the scheduler will now idle the core for
it's timeslice, in order to avoid continuously yielding the same thing
over and over.

kernel/scheduler: Pass in system instance in constructor
Avoids directly relying on the global system instance and instead makes

This also allows removing dependencies on some global accessor functions
as well.
