[FIX] tools: vendor werkzeug.urls

In latest versions of werkzeug, the `werkzeug.urls` module has been
reduced to remove feature present in urllib.parse. This commit vendored
the old version to avoid breaking compatibility with older versions of
odoo on ubuntu Noble, without adapting the whole codebase. This
should/may be removed in stable by adaptaing eveything to urlib.

This version of the lib was minimalized to avoid redondunce with feature
still present in werkzeug.urls. Some unused features in odoo are still
vendored for ease but are not exposed on the werkzeug.urls for now.
