Add 'info memory_size_summary' command which is a sibling
of QMP command query-memory-size-summary. It provides the
following memory information in bytes:
* base-memory - size of "base" memory specified with command line option -m.
* plugged-memory - amount of memory that was hot-plugged.
If target does not have CONFIG_MEM_HOTPLUG enabled, no
value is reported.
