Make Document.inputEncoding an explicit alias of Document.characterSet

Document.inputEncoding has been revived in the DOM Standard:
https://www.w3.org/Bugs/Public/show_bug.cgi?id=27435
https://dom.spec.whatwg.org/#document

Drop the FIXME in XMLHttpRequest::send, as per spec the charset should
always be UTF-8:
https://xhr.spec.whatwg.org/#the-send()-method

This is internal refactoring; no observable change intended.
