Automatic update from web-platform-tests Make window.scroll* promises resolve at the end of a scroll - This completes the Window hookup and passed an existing WPT. - This CL also fixes no-op scrolls, without which another existing WPT `window-scroll-arguments.html` would be failing with the promise hookup here. - A similar hookup CL for Element landed recently without us noticing the above problem there because of missing test coverage. This CL fills the coverage through `element-scroll-arguments.html`.

This test makes sure that calling the element scrolling methods with a single

non-dictionary argument or with a dictionary whose 'behavior' field is invalid

throws an exception.
