Fix Linkit linking issues around Media entities and brakes Layout Builder behaviors

Problem/Motivation

I faced two issues on linkit module, when using links around image and when trying to remove the same link. This is related to #3158783: Links around media images break when edited, using Linkit and CKeditor & #3201405: Edit internal link and remove the URL breaks layout builder

Steps to reproduce

1- Add an image using CKEditor.
2- Add a link around the image.
3- Save the content.
4- You will have an error Drupal\Core\Entity\EntityStorageException: The "" entity type does not exist.
5- Try to edit the link and remove it.
6- It will clean the HTML attributes but the link will still exist, and the error will appear again.

Proposed resolution

Add the patch fixes from:

• #3158783: Links around media images break when edited, using Linkit and CKeditor
• #3201405: Edit internal link and remove the URL breaks layout builder
