We used to only reassign if flags changed

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: 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

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.

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

This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

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 :)
