Error when removing a phycics node during a physics callback

* This behavior is not allowed, the error text suggests using call_deferred().
* Added a check in Node::remove_child to prevent future crashes of this type.
* Fixed a performance regression introduced by #36244.

Fixes #63718, probably other crashes too.
