Add NR_BALLOON_PAGES counter to track memory used by balloon drivers and

In balloon_page_enqueue_one(), we perform a
__count_vm_event(BALLOON_INFLATE)
and in balloon_page_list_dequeue
__count_vm_event(BALLOON_DEFLATE);
Should we maybe simply do the per-node accounting similarly there?
I think the issue is that some balloon drivers use the
balloon_compaction interface while others use their own.
This would require unifying all the drivers under a single api which
may be tricky if they all have different behavior
