Since access token validation protocol is outside the scope of the OAuth 2.0 specification, what protocol does MessageSight use to validate an access token with the authorization server?

The access token is validated with the authorization server using HTTP/S. You're completely correct that this is outside the OAuth 2.0 specification, so I guess you'd just consider this a convention. The specification doesn't include a lot of the technical details that you need to use it in practice.
