Show an user facing error message when an entity cannot be copied

[yaustar]

Attempt to copy a VERY large entity structure in the hierarchy, if it's too large, a console error occurs but no message is given to the user saying why it cannot be copied.

clipboard:set (editor.method error)
DOMException: Failed to execute 'setItem' on 'Storage': Setting the value of 'playcanvas_editor_clipboard' exceeded the quota.

I can show this issue in a private project.

Oh interesting didn't know that can happen

Same. The entity in question is crazy massive 😅 I struggled to find another project that would also break the clipboard.
