• Add separate configs for the email and sms channel in username recovery.

Related issues

• SMS support for username recovery flow wso2/product-is#21180

Important notes

• We are not removing the previous username enable config which is used to disable the connector when both email and sms channels are disabled.
• To keep the backward compatibility we are using default value of the email channel as username enable value.

As I noticed for SMS based password recovery we have handled the configuration in a different way[1]. Isn't it inconsistence?
