[Merge M53] Run autofill-profile de-dupe after sync starts if sync is enabled.

This CL updates the PersonalDataManager to run autofill profile
de-duplication (if enabled) at the appropriate time, depending on
whether autofill profile sync is enabled.

If sync is not enabled, profile de-duplication is run after the
data is initially loaded.

If sync is enabled, profild de-duplication is run after the sync
first becomes active.

In all cases, de-duplication is only run once for a given version
of chromium.
