Bug 1760276 [Wayland] Avoid to use move-to-rect when possible r=emilio
Due to move-to-rect limitations (https://gitlab.gnome.org/GNOME/gtk/-/issues/1986) we try to avoid it when it's possible. - Use plain popup resize/movement when popup is places inside of application toplevel window. - Hide moved/scaled popup window only when move-to-rect is used. - Clear mMoveToRectPopupRect before any move/resize and use Wayland compositor to place/size the window. Differential Revision: https://phabricator.services.mozilla.com/D141601
