Lioncash 4c2ed2706e core/memory: Introduce skeleton of Memory class
Currently, the main memory management code is one of the remaining
places where we have global state. The next series of changes will aim
to rectify this.

This change simply introduces the main skeleton of the class that will
contain all the necessary state.
