This leverages MSAL to support SNI auth with the sync CertificateCredential (closes #10816). I've tested this manually and will add a live test in a later PR. Adding equivalent support to the async CertificateCredential is tracked by #13349.

We need the private key and fingerprint in both cases. send_certificate=True means we need to include the cert content as well.

Yes. But if we only want to use the method in this model, shouldn't we use _extract_cert_chain? Or we may want to use it in other models in the future?
