mm: rename CONFIG_BALLOON_COMPACTION to CONFIG_BALLOON_MIGRATION
While compaction depends on migration, the other direction is not the
case. So let's make it clearer that this is all about migration of
balloon pages.
Adjust all comments/docs in the core to talk about "migration" instead of
"compaction".
While at it add some "/* CONFIG_BALLOON_MIGRATION */".
