Revert 221284 "Pepper: Move FileRef to the "new" resource proxy."

> Pepper: Move FileRef to the "new" resource proxy.
> 
> This change moves the FileRef implementation from the previous one in the "old"
> resource model (ppb_file_ref_impl.cc) to the "new" resource model
> (pepper_file_ref_host.cc), and from the renderer to the browser.
> 
> As many as possible of the supporting changes were split off to other changes
> to minimize the size of this change. Unfortunately, a lot of changes for
> URLLoader had to be rolled into this change.
> 
> The data structures for CreateInfo have changed, and all users of FileRef have
> to be moved over, which is what causes this change to be so large.
