#render_template_to_object and #render_partial_to_object are private

Apparently it had not been clear what visibility they should assume
when they were initially created at rails#35265,
then a big refactoring took place at rails#38594
after which they remain intact.

So I think they can now become properly private as they are nodoc and
not refered to but from within the same class.
