return type hint for endUse()

The `endUse()` method is returning a QueryClass of a related table. So we can not use `@return $this` here (see #560). At the moment the return type of `endUse()` is `Criteria`. With this PR every Query base class gets a `@method` tag for `endUse` with return type of all possible (related) classes. So autocompletion and type inference in IDE is possible.
