Sam Atkins 1e53768f1b LibWeb: Combine background-repeat-x/y pseudo-properties
While right now this doesn't save much complexity, it will do once we
care about multiple background layers per node. Then, having a single
repeat value per layer will simplify things.

It also means we can remove the pseudo-property concept entirely! :^)
