icon fallback concept without QIcon::fallbackSearchPaths (bug #62106)
* FigureWindow.cc (FigureWindow): do not use fromTheme
* ToolBarButton.cc: include QString and gui-preferences-global.h;
(get_icon): do not use fromTheme
* gui-preferences-global.h: define QStringList with exisiting icon
fallback paths togehter with an enumeration for the list inidices
* octave-dock-widget.cc (label_dock_widget): use ressource_manager::icon
instead of fromTheme, use constants from gui-preferences for icon paths
instead of literal strings in style sheets
(make_window): dito
(make_widget): dito
* resource-manager.cc (resource_manager): initialize m_icon_fallbacks;
(config_icon_theme): collect fallback paths in a string list depending
on selected icon theme;
(icon): test existance of icon in current theme, if not, test the
fallback locations;
* resource-manager.h: new string list m_icon_fallbacks
