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.
