Changing the translate back-end to use the Google Translate element.
When the user indicates that a page should be translated, the browser first fetches the Google Translate Element JS code. It then sends it to the renderer, which injects the script in the page, waits for the Translate element to be initialized and then calls the translate method on it. The TranslationService class previously used to translate text chunks is now unused and has been removed. Some of its static methods that are still used have been moved to the TranslateManager class. This CL also implements the "revert" translation behavior. BUG=35474,37778,35553,39375 TEST=Test the translation feature extensively.
