Change the event type of chrome.input.ime.onKeyEvent, and add chrome.input.ime.keyEventHandled.

To support asynchronous event, chrome.input.ime.onKeyEvent will be accept opt_extraInfo parameter.

In chrome_extensions.js chrome.input.ime.onKeyEvent is defined as ChromeEvent.
But ChromeEvent.prototype.addListener accepts only one parameter.
So this cl defines ChromeInputImeOnKeyEventEvent like WebRequestOnErrorOccurredEvent.
