Sync: move v2 classes in chrome/internal_api to syncer_v2 namespace.

This changes namespace of some of internal API Bismarck classes from
syncer to syncer_v2 to make it easier to distinguish the new code from the
current Sync implementation. The change includes a bit of dependency
cleanup. This is a fairly trivial change, but a good way to see most of
Bismarck classes and how they are integrated in the rest of the code.
There are two more separate issues to make a similar namespace change
in sync/engine and components/sync_driver directories.
