Adds TabContents/RenderView observers for automation/testing messages.

The RenderViewObserver currently sends two messages to the browser related
to tracking client redirects, which is needed for determining whether to
wait for a future navigation.

This is particularly needed to wait correctly in chromedriver for form
submissions and javascript redirects. However, timed redirects still need
to be considered.
BUG=none
