Sam Atkins 269810b954 LibWeb: Break friendship between CSS Declaration and Parser
This means deviating slightly from the spec in order to construct a
fully-initialized Declaration instead of creating an empty one and then
poking at its internals.

DeclarationOrAtRule should probably use a Variant, but for now, making
its Declaration member optional is quick and easy.
