Kernel: Per processor information is now stored in class Processor
...
This allows us to allocate processor stacks, and other per processor
structures dynamically in runtime. Giving processor stack to
ap_trampoline feels super hacky, but it works for now.

Kernel: Rewrite all kernel mutexes
...
Now SpinLock is actually just a spin lock and I added a Mutex that
does the same as the old "SpinLock". This is in preparation for
starting to support smp and making the kernel smp safe. This commit
also removes obsolete PageTableScope and CriticalScope which should
now be used by alternative APIs.
