Add the possibility to use a field without setting the node bundle

I really want this feature too.

Here's a patch that allows choosing a bundle or choosing "Any bundle". It seems to be working for me and I don't think it introduced any BC problems.

Here's a few screenshots.

Bundle selected:

"Any bundle" selected

A minor UX bug unfortunately is that the empty option label doesn't make sense on the field select.

That would be easy to fix. I'm not interested in doing that until there's review though.

In my opinion the option danflanagan8 added is what should be added. Let the end user choose a bundle or any bundle. Therefor I created a MR with that patch and hidden all other patches.

But I follow that the select options need some update to reflect the correct text shown. I'll pick this up.

Adjusted the empty bundle option and reverted the empty field option
