WindowServer: Let clients mark windows as stealable by specific clients
This implements window stealing in WindowServer, which allows clients to mark a window they own as 'stealable' by another client. Indicating that the other client may use it for any purpose. This also updates set_window_parent_from_id so that the client must first mark its window as stealable before allowing other clients to use it as a parent.
