Closes: https://github.com/systemd/systemd/issues/19246 Some FIDO2 devices allow the user to choose whether to use a PIN or not and will HMAC with a different secret depending on the choice. Some other devices (or some device-specific configuration) can instead make it mandatory. Allow the cryptenroll user to choose whether to use a PIN or not, but fail immediately if it is a hard requirement. Record the choice in the JSON-encoded LUKS header metadata so that the right set of options can be used on unlock.
