Change Server methods

- Rename `Server::respondToWellKnownRequest()` tp the more descriptive `Server::respondToOpenIdMetadataRequest()`
- Rename `Server::respondToJwksRequest()` to `Server::respondToJwksMetadataRequest()` for the sake of consistency
- Add an empty `Server::respondToDynamicClientRegistrationRequest()` that can already be consumed by implementing parties
