This patch introduces code generation for the WindowServer IPC with its clients. The client/server endpoints are defined by the two .ipc files in Servers/WindowServer/: WindowServer.ipc and WindowClient.ipc It now becomes significantly easier to add features and capabilities to WindowServer since you don't have to know nearly as much about all the intricate paths that IPC messages take between LibGUI and WSWindow. The new system also uses significantly less IPC bandwidth since we're now doing packed serialization instead of passing fixed-sized structs of ~600 bytes for each message. Some repaint coalescing optimizations are lost in this conversion and we'll need to look at how to implement those in the new world. The old CoreIPC::Client::Connection and CoreIPC::Server::Connection classes are removed by this patch and replaced by use of ConnectionNG, which will be renamed eventually. Goodbye, old WindowServer IPC. You served us well :^)
