Issue:

• Introduce new authenticator properties: DefinedBy product-is#21111

With wso2/carbon-identity-framework#5938 PR, we have introduced following new properties for authentication configs and authenticator instances.

• DefinedBy - to indicate whether the authenticator is system-defined or user-defined.

1. SYSTEM: Sytem defined authenticators, all the existing authenticators are this type.
2. USER: User defined authenticators, all the custom authenticators of authentication extension come under this type.

• AuthenticationType - To indicate whether authenticator is one of following

1. IDENTIFICATION: This authenticator collects the identifier and authenticates user accounts.
2. VERIFICATION_ONLY: This authenticator can only verify users in the second or subsequent steps of the login
   process.

With this PR following changes are added.

1. Set new authenticator property DefinedBy for the FederatedAuthenticatedConfig and LocalAuthenticatorConfig objects that pass to the framework.
2. Retrieve the DefinedBy property from the config and display them in the APIs.
3. Update yaml files to accommodate above point.
