* fix(oidc): return bad request for base64 errors
We've recently noticed an increased amount of 500: internal server error status returns on zitadel cloud.
The source of these errors appear to be erroneous input in fields that are supposed to be bas64 formatted.
```
time=2024-04-08T14:05:47.600Z level=ERROR msg="request error" oidc_error.parent="ID=OIDC-AhX2u Message=Errors.Internal Parent=(illegal base64 data at input byte 8)" oidc_error.description=Errors.Internal oidc_error.type=server_error status_code=500
```
Within the possible code paths of the token endpoint there are a couple of uses of base64.Encoding.DecodeString of which a returned error was not properly wrapped, but returned as-is.
This causes the oidc error handler to return a 500 with the `OIDC-AhX2u` ID.
We were not able to pinpoint the exact errors that are happening to any one call of `DecodeString`.
This fix wraps all errors from `DecodeString` so that proper 400: bad request is returned with information about the error. Each wrapper now has an unique error ID, so that logs will contain the source of the error as well.
This bug was reported internally by the ops team.

This PR adds support for OAuth2 token revocation of V2 tokens.
Unlike with V1 tokens, it's now possible to revoke a token not only from the authorized client / client which the token was issued to, but rather from all trusted clients (audience)
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.
