Change the way lifetime works in ext/libxml and ext/dom Previously, a node could be freed even when holding a userland reference to it. This resulted in exceptions when trying to access that node after it has been implicitly or explicitly removed. After this patch, a node will only be freed when the last userland reference disappears. Fixes GH-9628. Closes GH-11576.
