dev(sched): Improvements and work in progress fixes.

what?

 - The main algorithm got improved for real time tasks, and SMP usage.
	- The SMP usage was present before, I just reintroduced it after
	realizing that it won't scale well from what I have right now.
 - Also removed weird implementations quirks from previous sketch.
	- Such as the core 0 being reserved for the boot core.
 - Also moved FS init code after IDT initalization.
	- To avoid weird FS format behavior.
 - Wrap HPET signature in a macro.

next?

 - Work on the HAL's userspace transition mechanism.
