Move some files from chrome/renderer/pepper to components/nacl/renderer/

Move pnacl_translation_resource_host files as they have no dependencies of the chrome layer.

Move the creation of the nacl private interface (ppb_nacl_private_impl) to the components directory : 
it requires to remove the IsOffTheRecord member of the interface (to not depend on chrome/)
but it's not used anyway.

This is part of an effort to componentize NaCl code.
