[FR] Provide more details for SENDER_ID_MISMATCH if I have permission to see across projects

**Is your feature request related to a problem? Please describe.**

As a developer, I'd like to be able to verify an ID token across all projects that I have access to in Firebase. There is an existing API to do so today but requires specifying a project ID and providing the correct credentials for each project.

https://firebase.google.com/docs/auth/admin/verify-id-tokens#verify_id_tokens_using_the_firebase_admin_sdk

**Describe the solution you'd like**

During debugging, the SENDER_ID_MISMATCH response tells you that a token is registered against a different project than it's being used for, but does not tell you what project it is. Since the Firebase portal knows which projects I already have access to, it would be helpful to have this built into the Firebase portal where, if I have access to the project, it can tell me the project it is registered to. Often, we will have dev/prod Firebase projects and provide the config during build time; this would help us debug the issue if they got mixed up.

**Describe alternatives you've considered**

It's possible to write a version of this on our own using a script that loads credentials and tests tokens against each project I have access to, but is not very friendly to get the necessary credential files for the script.

**Additional context**
I was forwarded here from the android SDK repo https://github.com/firebase/firebase-android-sdk/issues/5545

No se nombran archivos del repositorio ni pruebas. Primero determina si esta solicitud corresponde a firebase-admin-node o al portal de Firebase y, después, revisa la API existente de verify-ID-token y el issue vinculado del Android SDK. Se considerará completado cuando exista un alcance de implementación acordado que pueda identificar el proyecto registrado del token únicamente cuando el usuario tenga acceso a él.
