The content client should be the glue between the content layer and the chrome
embedder, and carry no state itself. If you want to store one copy of the image
setting rules, you can store it them in the ChromeRenderProcessObserver.

Done. But, the ChromeRenderProcessObserver is not created in the tests, so I
added a ha.. err, indirection here: ChromeContentRendererClient holds a pointer
to the image setting rules. Normally ChromeRenderProcessObserver sets it to
point to its member, but also the tests can set it.
