Graphql/AuthorizeTypes: Add offenses for empty authorize statements

What does this MR do and why?

Describe in detail what your merge request does and why.

An authorize statement with no arguments is the same as not having an authorize statement at all. So, we should flag an offense if authorize does not have any arguments.

Bad

This currently does not result in any offenses.
