Reviewed by Darin Adler.

Update the dispatchSimulatedClick() to take option enums for dispatching events.

* dom/SimulatedClickOptions.h: Added. Define two options enums. One tracks which mouse
events to send. The other determines whether to force the element to repaint.

* dom/EventDispatcher.cpp:
(WebCore::EventDispatcher::dispatchSimulatedClick): Refactor to use the option enums.
* dom/EventDispatcher.h:
(EventDispatcher): Update function signature.

* dom/Node.cpp: Refactor parameters to use the options enums rather than booleans.

* dom/Node.h:

Refactor. Remove redundant comments.
