Kernel: Simplify interrupt management

Browse source 
The IRQController object is RefCounted, and is shared between the
InterruptManagement class & IRQ handlers' classes.

IRQHandler, SharedIRQHandler & SpuriousInterruptHandler classes
use a responsible IRQ controller directly instead of calling
InterruptManagement for disable(), enable() or eoi().

Also, the initialization process of InterruptManagement is
simplified, so it doesn't rely on an ACPI parser to be initialized.
