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.
