Changed ChromeURLDataManager to a ProfileKeyedService and made a Factory for it.

having just read through about 50 files where this exact pattern is used, I
would suggest creating a utility function in ChromeURLDataManager so you can
just do:

  ChromeURLDataManager::AddDataSource(
      profile, CreateMediaInternalsHTMLSource());

or in many cases, like this one,

  ChromeURLDataManager::AddDataSource(
      Profile::FromWebUI(web_ui), CreateMediaInternalsHTMLSource());

Done on this one instance. Waiting on positive review before applying it to
everything else.
