While Origin is defined in the HTML spec - this leaves us with quite an awkward relationship as the URL spec makes use of AO's from what is defined in the HTML spec. To simplify this factoring, relocate Origin into LibURL. (cherry picked from commit dc401f49ea7e861064484e79594e35c3d93000ae; amended to fix minor conflicts due to serenity not (yet?) having a LibUnicode/Segmenter.h include in Document.cpp, and due to BrowsingContext already having LadybirdBrowser/ladybird#2358 in serenity)
