Attempt 4: Prevent reparenting a block with itself (#38747)

Browse source 
* More concisely reparent, ensuring we don't go too shallow or too deep in this process. Fixes #38357

* More explicit reparenting, with a short circuit for a common case

* We need new_block to have a parent, otherwise we lose context with this approach

* Remove duplicate parent assignment

* Change callers of Block.copy to not use exclude_parent=True, when including the parent, exclude tasks
