LibGUI+WindowServer: Separate window manager IPC from regular IPC

Browse source 
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.
