Niels Dossche 003ebdd039 Fix GH-9628: Implicitly removing nodes from \DOMDocument breaks existing references 
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.
