https://bugs.webkit.org/show_bug.cgi?id=261016

Reviewed by Chris Dumez.

Added some tests for mutating DOM during replaceChildren's tree mutating operations.

Also refactor the code in ContainerNode::replaceChildren by merging some aspects of
Node::convertNodesOrStringsIntoNode into the function so that all node removal &
insertion the logic will be in one place.
