Fixed #32824 -- Improved performance of NodeList.render().

Browse source 
This avoids the following:
 - checking that each item in the nodelist is a subclass of Node,
 - calling str() on the render_annotated() output, because it's
   documented that Node.render() must return a string,
 - calling mark_safe() on the output, when the value to be wrapped is
   definitively known to be a string because the result of ''.join()
   is always of that type,
 - using an intermediate list to store each individual string.

:class:`~django.utils.feedgenerator.Atom1Feed`, and their subclasses now
emit elements with no content as self-closing tags.
* ``NodeList.render()`` no longer casts the output of ``render()`` method for
individual nodes to a string. ``Node.render()`` should always return a string
as documented.
