This PR adds events during the framegraph setup at the start of level rendering. These allow adding custom passes to the graph and enabling entity outline post-processing without any entities in view having active outlines.
The pre event is fired right after the "clear" pass is set up and the post event is fired right before the graph is executed.
Opening as a draft for now because I'm not totally sure whether the split into pre and post is actually useful or whether the pre event primarily for the outline stuff and people using mixins to precisely inject custom passes between vanilla passes is more suitable.
