LibGUI+WindowServer: Separate window manager IPC from regular IPC
With this patch the window manager related functionality is split out onto a new endpoint pair named WindowManagerServer/Client. This allows window manager functionality to be potentially privilege separated in the future. To this end, a new client named WMConnectionClient is used to maintain a window manager connection. When a process connects to the endpoint and greets the WindowServer as a window manager (via Window::make_window_manager(int)), they're subscribed to the events they requested via the WM event mask. This patch also removes the hardcoding of the Taskbar WindowType to receive WM events automatically. However, being a window manager still requires having an active window, at the moment.
