bc107d0b33 Kernel: Add SMP IPI support 
We can now properly initialize all processors without
crashing by sending SMP IPI messages to synchronize memory
between processors.

We now initialize the APs once we have the scheduler running.
This is so that we can process IPI messages from the other
cores.

Also rework interrupt handling a bit so that it's more of a
1:1 mapping. We need to allocate non-sharable interrupts for
IPIs.

This also fixes the occasional hang/crash because all
CPUs now synchronize memory with each other.

fe664965c2 Kernel: Change get_sharing_devices_count() in GenericInterruptHandler 
The new method' name is sharing_devices_count().
The Serenity Coding Style tends to not accept the word "get" in
methods' names if possible.

b201b23363 Kernel: Add Interrupt Management and Generic Interrupt Handler 
The GenericInterruptHandler class will be used to represent
an abstract interrupt handler. The InterruptManagement class will
represent a centralized component to manage interrupts.
