Improve async approach of form-method-dialog.html.

form-method-dialog.html had flaky timeouts and failures.  As described
in the bug, the flakiness may be caused by directly moving on to the
next testcase in the event handler for the current testcase. This
modifies the test to queue up the next testcase via setTimeout so it's
not entered until the current testcase finishes completely.

Remove redundant scheduleDelayedAction in Audio constructor

Setting the src attribute will trigger HTMLMediaElement::parseAttribute,
which already calls scheduleDelayedAction when src is modified.

This is already tested by LayoutTests/media/audio-constructor-src.html

Stop sending notifications of programmatic scrolls.

This code was part of the feature that allowed developers to
 hide the top controls (e.g. the url bar) by calling 
scrollTo. This feature was never launched and never will be. 
See bug for further details.

This effectively reverts the following patches:
