[PM-22136] Expose encrypt_fido2_credentials to support cipher encryption in TS clients (#331)

## 🎟️ Tracking

[PM-22136](https://bitwarden.atlassian.net/browse/PM-22136)

## 📔 Objective

The TS clients use fully decrypted FIDO2 credentials which need to be
re-encrypted separately before using the SDK to encrypt the rest of the
Cipher. Otherwise, the FIDO2 credential encryption key will be lost.

Once the decrypted FIDO2 Credentials are removed from the LoginView in
TS, this method can be removed.
