This PR adds support for userinfo and introspection of V2 tokens. Further V2 access tokens and session tokens can be used for authentication on the ZITADEL API (like the current access tokens).
This PR changes the information stored on the SessionLinkedEvent and (OIDC Session) AddedEvent from OIDC AMR strings to domain.UserAuthMethodTypes, so no information is lost in the process (e.g. authentication with an IDP)
This PR starts the OIDC implementation for the API V2 including the Implicit and Code Flow.
