migration: Merge ram_counters and ram_atomic_counters

Using MgrationStats as type for ram_counters mean that we didn't have
to re-declare each value in another struct. The need of atomic
counters have make us to create MigrationAtomicStats for this atomic
counters.

Create RAMStats type which is a merge of MigrationStats and
MigrationAtomicStats removing unused members.
