Kernel: Split Aarch64 CPU setup into two stages
...
Former aims to bring the processor itself into desired state,
while latter allows for additional initialization with heap available.

Kernel: Introduce stages in Aarch64 CPU initialization phase
...
Dropping to each exception level is now more explicit.

Kernel/aarch64: Add implementation of Processor::switch_context
...
This initial implementation makes it possible to actually context switch
between different kernel threads! :^)

Kernel/aarch64: Implement thread_context_first_enter
...
This requires two new functions, context_first_init and
restore_context_and_eret. With this code in place, we are now running
the first idle thread! :^)

Kernel/aarch64: Implement Processor::initialize_context_switching
...
This changes the stack pointer to the initial_thread stack pointer, and
pushes two pointers onto the stack that point to the initial_thread. The
function then jumps to the ip of the initial_thread, which will be
thread_context_first_enter, and hangs there because that function is not
yet implemented.

Kernel/aarch64: Add initial implementation of Processor::init_context
...
This does not handle everything correctly yet, such as setting the
correct state for running userspace applications, however this should be
enough to get kernel scheduling to work.

Kernel/aarch64: Implement tlb flushing

FIXME: There's still a lot to do like for example, port `quickmap_page`.
This does however get us further into the boot process than before.

Now that we merged all the Prekernel files into the Kernel files, we can
get rid of the Prekernel namespace as well.

the Prekernel from the aarch64 Kernel.

Kernel: Add initial implementation of Processor in aarch64
...
Instead of storing the current Processor into a core local register, we
currently just store it into a global, since we don't support SMP for
aarch64 anyway. This simplifies the initial implementation.
