svx: move lok's NotifyKit in the ruler to the SvxRuler super-class

We want to make the ruler work in other components and also not
only for horizontal orientation. For this we want the NotifyKit
already in the SvxRuler, which is used by all rulers. This change
moves the functionality to the from SwCommentRuler to SvxRuler and
partially reverts the previous attempt as changing the ruler
instance for vertical ruelr to SwCommentRuler caused test failures.
