This adds a SQLServer binary for Ladybird to make use of Serenity's SQL
implementation. This has to use the same IPC socket handling that was
used to make WebContent and WebDriver work out-of-process.
Unlike Serenity, Ladybird creates a new SQLServer instance for each
Ladybird instance. In the future, we should try to make sure there is
only one SQLServer instance at a time, and allow multiple Ladybird
instances to communicate with it.
