Fix the Node.replaceChild tests
That method first does "if node is a host-including inclusive ancestor of parent,
throw a HierarchyRequestError" and only then "if child’s parent is not parent,
throw a NotFoundError exception".

This is just the result of running --manifest-update on master; not sure

Implement ChildNode::before & ChildNode::after
Continued from #6536
The current implementations of `ChildNode::before` and
`ChildNode::after` do not match the WHATWG spec. This commit updates the
implementations to match the spec.
Our current implementation of `ChildNode::after` passes all the WPT
tests. So I made sure to add a regression test that failed with the
current implementation. There are a few other unit tests I added
to exhaust other corner cases I encountered.

Previous, it would return the original String straight from the
AttrValue, which might contain extraaneous whitespace. The spec
specifies to just join the tokens together with \x20
