Open Klipper under mouse also on wayland

On Wayland if Plasma had no focus when the shortcut was invoked

• the menu window is created as toplevel because it has no parent and there is no current focusWindow
• the application can't know the currrent cursor position We use a newly introduced request on plasma_surface to open under the cursor. As it can only be called before mapping a buffer to a surface, the menu is hidden before being shown again.
