Forward Webkit Gesture events to interested RenderViewObservers.

The ChromeRenderViewObserver overrides the RenderViewObserver::DidHandleGestureEvent virtual and
forwards the ChromeViewHostMsg_FocusedEditableNodeTouched IPC notification to the brower if the user
tapped on an editable field on the page. 

We will be handling this notification in the browser to display the Windows 8 on screen keyboard. That
in a subsequent CL.
