Renamed FaviconHandlerDelegate to FaviconDriver.

Note:
Currently FaviconTabHelper implements both FaviconClient and FaviconDriver.
A follow up CL will create a ContentFaviconDriver class that implements
FaviconDriver. FaviconTabHelper will then own an instance of the
ContentFaviconDriver, instead of inheriting from FaviconDriver.
