Kernel and System.Core: kernel related fixes and :boom: on User API.

- UserHeap.cxx: Document code and fix issue in ke_free_heap_internal.
- Scheduler: Rename ProcessManager to ProcessScheduler.

- The System API has been reworked to improve it's design, such as no
  more C++ to improve it's portability.

- Moved containers into it's own API.
