Circular dependencies in EntityReferenceRevisionsFieldItemList::hasAffectingChanges();

Hello, here is a new patch, it's work for me, I wanted to run the unit tests but there is always some missing dependences

I updated my patch. I kept the cache idea from @rabithk but I turn it into a stack to clear the cache out of recursion case.

I have tried to create a merge request for the change with an attempt to reset the static cache on save. I thought that this would address kernel tests breaking or other scenarios where the same entity is saved multiple times in the same request. Alas that did not prove to be the case.

I based the merge request on the work in #2. It still applies, had the original feedback from Berdir and because I could not tell what the intention between this and the changes in #7 + #8 actually are.

The postSave() from #10 will lead to missing reference to parent entity. See the image
