Very hackish implementation, but we now get actual registers at the
time of the interrupt happening

Kernel: kmalloc_eternal now updates the used/free values
...
I also improved the kmalloc_dump_info() formatting. We format the
values as 8-digit hex numbers since (atleast for now) the kmalloc
will always be under 4 GiB address and size :)

...
We don't have to invalidate page in AllocatePage() if we don't make
any changes. We also should not assert on deallocating non-present
pages, just return early :)

Kernel: I have no idea what this commit does

I had committed a change in IDT but reverted it now.
This propably only adds a spurious interrupt detection to common cpp
interrupt handler?

It didn't make sense that dprint was defined in Serial.h.
