Support for Microsoft's oid parameter

Ory now supports the use of Microsoft's oid (Object ID) as a subject identifier. By default, Microsoft uses the sub field from the OIDC id_token, which can vary with each app registration. This can create challenges when migrating users between app registrations, as the sub value is not consistent across apps.

The new support allows using the oid field or the id field from the https://graph.microsoft.com/v1.0/me endpoint for user identification. This ensures a stable and unique identifier, simplifying migrations and cross-service user recognition.
