feat(OIDC): handle logout hint on end_session_endpoint (#10039)

# Which Problems Are Solved

The OIDC session endpoint allows to pass a `id_token_hint` to identify
the session to terminate. In case the application is not able to pass
that, e.g. Console currently allows multiple sessions to be open, but
will only store the id_token of the current session, allowing to pass
the `logout_hint` to identify the user adds some new possibilities.

# How the Problems Are Solved

In case the end_session_endpoint is called with no `id_token_hint`, but
a `logout_hint` and the v2 login UI is configured, the information is
passed to the login UI also as `login_hint` parameter to allow the login
UI to determine the session to be terminated, resp. let the user decide.

# Additional Changes

Also added the `ui_locales` as parameter to handle and pass to the V2
login UI.

# Dependencies ⚠️ 

~These changes depend on https://github.com/zitadel/oidc/pull/774~

# Additional Context

closes #9847
