[FIX] base, website: fix routing redirect

Redirect_type was renamed from 3xx to redirect_3xx, but name is used as http
status code. It is better a redirect(301) instead of redirect(redirect_301)

Re-add the bind_to_environ, it was removed because it seems not useful, but
once you are behind a proxy, werkzeug need the environ to find the correct
hostname and more ... Transformed relative url into absolute by werkzeug was
wrong.

closes odoo/odoo#37733
