Ladybird: Implement WebDriver for Ladybird :^)

Browse source 
This adds a WebDriver binary for Ladybird to make use of Serenity's
WebDriver implementation. This has to use the same IPC socket handling
that was used to make WebContent work out-of-process. Besides that, we
are able to reuse almost everything from Serenity.
