hgweb: don't redundantly pass templater with requestcontext (API)

The requestcontenxt has a ``tmpl`` attribute to access the
templater. We don't need to pass the templater explicitly when
passing a requestcontext instance.

.. api::

   Various helper functions in hgweb.webutil no longer accept a
   templater instance. Access the templater through the
   ``web`` argument instead.
