link undo in main window to editor if the latter has focus (bug #44402)
* file-editor.cc (editor_tab_has_focus): helper function checking whether
an edit area has the focus;
(copyClipboard, pasteClipboard, selectAll): use this helper function;
(do_undo): new slot for the undo action triggered from the main window
* file-editor.h: new helper function and new slots
* main-window.cc (handle_undo_request): emit a signal for undo instead of
undoing in terminal window when terminal does not have focus
* main-window.h: new undo signal
* octave-dock-widget.cc (octave_dock_widget): connect undo signal from
main-window to new virtual slot;
* octave-dock-widget.h: new virtual slot do_undo, doing nothing
