Add support to automatically create a clone for the existing inline blocks in the layout in Layout Library

Problem/Motivation

I suggest supporting adding inline blocks in the predefined layouts, so when creating a new node using this layout it will automatically create a clone for the existing inline blocks in the layout.

Steps to reproduce

1- Create a custom block called accordion.
2- Create another custom block called the accordion section.
3- Add the entity reference field to the accordion block to reference the accordion section block.
4- Create a new layout from the layout library.
5- Add an accordion block to a section.
6- Create a node with the created layout.
7- It will create the accordion block but it will keep using the original accordion sections (inline-block) that are used in the layout.

Proposed resolution

There is exist issue opened for layout library module, and we can use the patch from it for now. #3273160: Support inline blocks in layout
