Create content::UtilityThread interface and make chrome code use that. This interface is implemented

by the UtilityThreadImpl class in content\utility\utility_thread_impl.cc/.h which are renamed incarnations

of the content\utility\utility_thread.cc/.h files.

Changes as part of creating a content API.

BUG=98716
