Breaking: #85080 - Method "isEnabled()" added to RenderableInterface and FinisherInterface

See Issue #85080

Description

A new method isEnabled() has been added to the RenderableInterface as well as the FinisherInterface.

Impact

Third party code implementing these interfaces and not extending AbstractRenderable or AbstractFinisher will cause a fatal error if used in a form.

Affected Installations

Instances with third party code implementing these interfaces and not extending AbstractRenderable or AbstractFinisher.

Migration

Third party code implementing these interfaces must be updated to implement the isEnabled() method, preferably by extending AbstractRenderable (or one of its subclasses) or AbstractFinisher.
