Kernel: Map multiboot2 memory in PageTable initialization
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.

Kernel: Start using multiboot2 instead of multiboot
This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.

Kernel: Kmalloc now has its memory statically allocated
We don't use the memory map given by bootloader since this automatically
maps the memory to a available space.

My brain has been melting since I'm getting very random bugs.
I hope I can debug them better with ubsan :)
