Convert indirect uses of TestingFactoryFunction

TestingFactoryFunction is a simple function pointer. It is
deprecated in favor of TestingFactory which is a Callback<>.
Convert indirect uses by using base::BindRepeating() in all
invocation of SetTestingFactory/AddTestingFactory.

This converts uses in src//chrome/browser/ui/webui.
