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: Move interrupt status stuff to Processor.h
...
SpinLocks are now locked with processor id instead of thread id. This
allows having multiple processors running while scheduler is not yet
activated.
