Fix broken cache invalidation with deallocated and reallocated document node

The original caching implementation had an oversight in combination with
the new lifetime management in DOM for 8.3.
The modification counter is stored on the document object itself, but as
that can get deallocated when all references disappear, stale cache data
can be used. Normally this isn't a problem, unless getElementsByTagName is
called not on the document but on a child node. Fix it by moving caching
data into the ref object, which will outlive all nodes from a document
even if the document object disappears.

Closes GH-12338.

Optimize checks for DOMParentNode and DOMChildNode

Because we check the list with dom_sanity_check_node_list_for_insertion()
before dom_is_node_in_list(), then we don't have to check the object
type anymore in dom_is_node_in_list(), because
dom_sanity_check_node_list_for_insertion() will have already done that.

Make DOMChildNode::remove() run in O(1) performance

This method had some useless logic in it. It checked whether the child
node is a child of its parent, which is always true of course.

Make DOMChildNode::remove() run in O(1) performance

This method had some useless logic in it. It checked whether the child
node is a child of its parent, which is always true of course.
But I know where this check comes from, if you follow the spec closely
you'll find that the spec used to have explicit child and parent
arguments for the removal algorithm [1].
That's because that algorithm is written in a generic way, where the
parent and child arguments might not come from the same subtree.
However, in this particular case it *is* always the case that the child
is a child of its parent. The checks weren't needed back then for
DOMChildNode::remove(), and are still not needed today.

Fix GH-11625: DOMElement::replaceWith() doesn't replace node with DOMDocumentFragment but just deletes node or causes wrapping <></> depending on libxml2 version

Depending on the libxml2 version, the behaviour is either to not
render the fragment correctly, or to wrap it inside <></>. Fix it by
unpacking fragments manually. This has the side effect that we need to
move the unlinking check in the replacement function to earlier because
the empty child list is now possible in non-error cases.
Also fixes a mistake in the linked list management.

Closes GH-11627.
