Convert ui/aura 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 ui/aura
to the recommended methods/types.
