Fix entity clone issue: custom block with paragraph on layout builder fails to clone correctly

Problem/Motivation

I faced an issue with entity clone module when tried to clone a node that used layout builder on it and inserted a custom block with an inline paragraph or block.

Steps to reproduce

• Create a paragraph type called "Rich Text" with a single rich text field
• Create a block type called "Paragraph Text Block" that has a single paragraph field that allows only "Rich Text" paragraph types
• Create a Page type that has layout builder enabled
• Create a node using the Page type bundle
• Go to "Layout" on the node you created
• Add a new block to the layout: Add Block -> Create custom block -> click "Paragraph Text Block", enter the text "block title" for the title and "block body" for the body and click Add block
• Click Save Layout
• Click clone to clone the node
• Go to "Layout" on the cloned node
• Click the quick edit icon and then click "Configure"
• Change the title to "block title modified" and the body to "block body modified" and click Update
• Go back to the original node and notice the title of the original block displays, "block title", but the body does not display, "block body"

Proposed resolution

The clone process should clone the node with it's layout and all inline blocks.
