Convert third_party/libaddressinput/chromium away from base::Bind/base::Callback

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 all uses of base::Bind/base::Callback in
third_party/libaddressinput/chromium to the recommended
methods/types.
