Delete Automation[Tab/Renderer]Helper and fix users.

For Chrome Endure, use the memory benchmarking V8 extension instead.
For the old ChromeDriver, just mark the messages as deprecated on the client side. I'll remove all the old ChromeDriver code later. I want to keep it here since we release ChromeDriver from HEAD, and we might need to do critical fixes for Chrome 28 and below still.
BUG=240580
