[memap] Removing stack/heap and minor improvements

- Removing stack & heap (dynamic) RAM information
  This information was misleading and shouldn't be shown in memap.
  E.g. each task may have its own stack region configured at run time.

- Adding 'bytes' unit in the total memory info

- Right aligment of numbers, so it is easier to compare numbers
