Fixes#38209
OAuth2-linked accounts that sign in via the password form were still
redirected to the provider end_session_endpoint on logout because the
redirect was keyed off account LoginType.
Store the session sign-in method (password vs oauth2) and only use
RP-initiated OIDC logout when this session was authenticated via OAuth2.
Sessions without the new key keep the previous LoginType behavior.

Fix#880
Design:
1. A global setting `security.TWO_FACTOR_AUTH`.
* To support org-level config, we need to introduce a better "owner
setting" system first (in the future)
2. A user without 2FA can login and may explore, but can NOT read or
write to any repositories via API/web.
3. Keep things as simple as possible.
* This option only aggressively suggest users to enable their 2FA at the
moment, it does NOT guarantee that users must have 2FA before all other
operations, it should be good enough for real world use cases.
* Some details and tests could be improved in the future since this
change only adds a check and seems won't affect too much.
