hmp: introduce 'info memory_size_summary' command 



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.
