Kernel: MMU can now provide info about virtual address space

Kernel: 64 bit MMU now properly identity maps kernel

Kernel: namespace and function renames
...
MMU moved to namespace kernel
Kernel::Memory::Heap moved to just Kernel
MMU::map_{page,range} renamed to identity_map_{page,range}
Add MMU::get_page_flags

Kernel: Add barebones per process virtual addresses
...
We now assign every (userspace) process its own MMU which we load
in scheduler. This allows every process to have separate virtual
address space.
This is very hackish implementations but it works for now

Kernel: Add some bareboness functionality to map virtual addresses

Kernel: Rename MMU::{un,}allocate... to MMU::{un,}map
...
This is more appropriate name for the behaviour :D

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.

Kernel: Move kmalloc and MMU to Memory directory

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

Kernel: MMU now takes flags when allocating pages

All: rename every function from UpperCamelCase to snake_case
...
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

Kernel: Add constructor and destructor to MMU

Kernel: Improve MMU
...
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: Finally managed to get 64-bit working
...
I had weird problems with interrupts but everything should work now
