Baitinq d6bb110d89 LibWeb: Handle disabling of StyleSheet HTMLLinkElements
We now can handle dynamic updating of the disabled attribute of a <link>
of the stylesheet type.

We do this by hooking the adding and removing attribute's handlers and
dynamically loading/removing the stylesheet if it has been
enabled/disabled.
