Kernel: Replace IRQHandler with the new InterruptHandler class
System components that need an IRQ handling are now inheriting the InterruptHandler class. In addition to that, the initialization process of PATAChannel was changed to fit the changes. PATAChannel, E1000NetworkAdapter and RTL8139NetworkAdapter are now inheriting from PCI::Device instead of InterruptHandler directly.
