tdf#130857 qt weld: Implement QtInstanceWindow::present

The gtk_window_present doc says:

> Presents a window to the user.
>
> This may mean raising the window in the stacking order, unminimizing it,
> moving it to the current desktop and/or giving it the keyboard
> focus (possibly dependent on the user’s platform, window manager
> and preferences).

Therefore, call QWindow::requestActivate [2] for the Qt
implementation of weld::Window::present.
