Kernel: Introduce ProcessorSpecific<T> for per-CPU data structures

Browse source 
To add a new per-CPU data structure, add an ID for it to the
ProcessorSpecificDataID enum.

Then call ProcessorSpecific<T>::initialize() when you are ready to
construct the per-CPU data structure on the current CPU. It can then
be accessed via ProcessorSpecific<T>::get().

This patch replaces the existing hard-coded mechanisms for Scheduler
and MemoryManager per-CPU data structure.
