Use FPicker parentwindow argument to set file picker parent

the secret argument of xParentWindow already exists

here we use XSystemDependentWindowPeer and getWindowHandle to get the window
handle (which is a bit spurious in the wayland case but close enough) and then
look up all our toplevel frames for a matching one in order to get the
associated widget to use a a parent window

If the fpicker was still in fpicker we could get the vcl::Window for the
xParentWindow and get the frame directly from that but that necessitates
linking to toolkit, so do it this way instead
