Marien Zwart 46e3cd5aa2 Make HTMLHyperlinkElementUtils a mixin, not a NoInterfaceObject
Commit b8afa0abde9da31886a35f867d00a63a9cc69cc8 converted several interfaces
from NoInterfaceObject to mixins. It looks like it missed
HTMLHyperlinkElementUtils: it did update the interfaces that use
HTMLHyperlinkElementUtils (from "implements" to "includes"), but did not mark
HTMLHyperlinkElementUtils as a mixin.

Fix it, which makes HtmlAnchorElement gain useful functions like `set_href`.
