docs: clarification to terms used in hypervisor memory management

Memory management is hard[citation needed].  Furthermore, it isn't helped by
the inconsistent use of terms through the code, or that some terms have
changed meaning over time.

Describe the currently-used terms in a more practical fashon, so new code has
a concrete reference.
