base::Bind/base::Callback are deprecated in favor of either
base::BindOnce/base::OnceCallback or base::BindRepeating/
base::RepeatingCallback (depending on whether the callback
is invoked once or multiple time).

Convert some uses of base::Bind/base::Callback (this is a
multipart change) in components/prefs and services/prefs
to the recommended methods/types.
