Serializing children of void elements
https://bugs.webkit.org/show_bug.cgi?id=277440

Reviewed by Anne van Kesteren.

As per XML, if void elements contains children, the children also gets serialized,
as void elements concepts are only valid in HTML, So checking whether the syntax is xml, then it must have close tag except if it doesn't have children

@annevk seems some of the test were failing already (despite this changes) in LayoutTests/imported/w3c/web-platform-tests/domparsing/XMLSerializer-serializeToString.html

But am sure the test case i added would pass across all, but i cannot take specific logs regarding that.

You can use run-webkit-tests <path> --reset-results --no-build to generate test expectation for the test case and you should squash both changes into one commit.

Once you updated WPT test case, you can export them through script present in Tools/Scripts but @annevk would know how exactly to do (never did myself).

@Ahmad-S792 thanks will try that.

I see only this in stderr to check why test is failed.
But seems the title of the error is something in w3c test case was not passed. But log is irrelevant to it. Any idea @annevk
