TileMonitoring: Decoration fix.

Merged Scott Snyder requested to merge ssnyder/athena:decor.TileMonitoring-20230420 into 23.0

A DecorHandle should only be applied to elements of the container with which the handle was declared. This implies in particular that to attach decorations to a temporary object that is not recorded, one should not use a handle, but instead just a Decorator.

Set SuppressOutputDependence for EventCleaningTool.
