Add config action to copy entity displays

Uploading patch so that it can be used in Search Track issue of Drupal CMS.

As functionality mimics what field_ui module is doing, I placed the config action there, but maybe there is a better place for it. Also the tests are needed, I guess.

I'd call this a bug; the clone action as it currently exists doesn't work for entity displays.

There's 2 MRs but not sure which one to remove. Can 1 be closed or hidden.

a.dmitriiev → closed merge request !9871

Closing MR https://git.drupalcode.org/project/drupal/-/merge_requests/9871 in favor of https://git.drupalcode.org/project/drupal/-/merge_requests/9874 to have more general solution in place.

We've settled on !9874. I'm updating the issue summary to reflect that.

Uploading the updated patch to work with Drupal CMS Search track.

Updated approach works for entity displays now, also with wildcard

Code looks good and works, added comment as I'm not sure if this needs a doc update specific for config actions and/or recipes?

I think we might be able to fix setting the ID in entity displays and then this will be a little less special case.

So, good news and bad news.

The good news: yes, your idea seems to work. It supports this use case, and is tested:

core.entity_view_display.node.page.full:
  cloneAs: node.page.search_index

The catch is that this pattern won't support wildcards, which is specifically needed by @a.dmitriiev to get Drupal CMS's search indexing to work. So I had to expose createCopy() as an action method for that case:

core.entity_view_display.node.*.default:
  createCopy: search_result

This necessitated a change to the EntityMethod action, which doesn't account for the possibility of the method returning a different entity (i.e., a clone).

We will need to update the docs and I assume this should have a change record also.

Done! https://www.drupal.org/node/3482871 →

Amazing! Marking as RTBC.

Committed and pushed a1b47eafdb9 to 11.x and 9b7d24a6fad to 10.4.x. Thanks!

`createCopy` config action works as expected for Search Track of Drupal CMS recipe.

Thank you all!
