feat(kernel): Finalizing the first version of the user scheduler.

other:

 - Removed DmaPool into its own Kit.
 - ApplicationProcessor unit has been cleaned up.
 - Rename functions of MemoryMgr.
 - Use KIB instead of MIBs of stack.
 - Cleanup parts of the scheduler, and hw scheduler.
 - Use UD handler for INT 6.
