Kernel: Only compile lai for x86_64 targets

I will be dropping lai entirely soon. Once I get to writing AML
interpreter.

Kernel: Add fast page to page table
...
Add "fast page" to KERNEL_OFFSET. This is always present in page
tables and only requires changing the page table entry to map. This
requires no interrupts since it should only be for very operations
like memcpy.
I used to map all temporary mappings to vaddr 0, but this is much
better. C++ standard always says that nullptr access is undefined
and this gets rid of it.
Fixed some bugs I found along the way

Read x_dsdt address only if fadt's length contains it. Bochs seems
to have version 1 fadt without the x_* fields.

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.

I did not feel like implementing AML interpreter now, and wanted

at some point.

Kernel: MMU::get() is now MMU::kernel

MMU is can now be locked with RecursiveSpinLock.
Scheduler now has get_current_tid() that works before the Scheduler
is initialized. This allows RecursiveSpinLock usage early on.

Kernel: remove message from BAN::Error
...
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.
We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.
