Andreas Kling da526bac92 LibWeb: Don't invalidate layout tree on all DOM node removals ...

DOM nodes that didn't have a layout node before being removed from the
DOM are not going to change the shape of the layout tree after being
removed.

Observing this, we can avoid a full layout tree rebuild on some DOM node
removals.

This avoids a bunch of tree building work when loading https://x.com/
