Stop auto-generating entity-ce-display config

I'm going to just start on this -- I have the feeling I'll pick up opinions about BC (that are now vague) along the way and be better able to articulate them after doing a bit of work.

Needs review for the

So far, this is just moving code around (...) Maybe you want to merge this separately, before I do any real changes.

thx, this seems pretty good already. I dropped a few comments, please take a look!

Green, but I need one more nudge/feedback to be sure I need to fix addCeDisplayContent().

If this is considered "not relevant enough for alpha" I'll be happy to do that afterwards. I'm keeping notes on todos which I can transplant to a new issue:

- KernelTest for old situation (or at least look at that at the same time as: )
- clean up other tests and make sure I understand that the expected output is really as expected ( likely at the same time as converting other processors )
- this addCeDisplayContent() discussion.

Hm. After fixing a dumb bug, it turns out I have changed the tests too much.

on this now

ok, worked over it - as discussed with going with the semantics of "DISABLED" == not-existing as core does it usually also. Also extended test-coverage for making sure the fallback works correctly.

Thanks. Reviewed. No comments.

thx, merged!
