sceneUtils: Bundle splitting

[gtk-grafana]

I keep using methods in sceneUtils when generating external links, but then my module bundle size blows up and I wind up manually copying those methods into the app so I don't need to load all of scenes into the main module just to escape a variable or replace a pipe in an ad-hoc variable value.

Can we split out the sceneUtils into a bundle that can be loaded without including all of scenes?
Or at least the easy ones? (cloneSceneObjectState and registerVariableMacro might be difficult, but the rest seem to just need SceneObject, SceneObjectUrlValue, SceneObjectUrlValues, SceneObject, UniqueUrlKeyMapper)
