[4.x] Check the reference as part of recursive editing check

[duncanmcclean]

This pull request fixes an issue with the recursive editing check added in #9841, where it'd sometimes prevent editing unintentionally when it shouldn't be.

This issue can be seen in two scenarios:

• Eloquent Driver
  • Entries & terms are both using incrementing IDs.
  • When you're editing entry 1, then try to edit term 1 inline, it'd error out because the IDs are the same, even though they're different "things".
• Runway
  • Two resources, with a Has Many or Belongs To fieldtype configured.
  • In this example, we have a Product model and a Manufacturer model.
  • When you're editing Product 1, then try to edit manufacturer 1 inline, it'd error out because the IDs are the same, even though they're different models.

To fix this, we're now passing the item's "reference" to the publish container and checking it against the related item in the RelationshipItem component.

Fixes #10005.

We already have the concept of a "reference" for this purpose.

It's basically an id plus some other identifier. e.g. an entry's reference would be entry::123, an asset would be asset::container::path, a term would be term::topics::news::en, etc.

Please use this instead.

Do we still need that addition in Item.vue?

I've realised we don't need to check the id if we're now checking the reference. Simplified!
