listdlg: Make appearance and behavior more Matlab compatible (bug #46026)

* dialog.h, dialog.cc (ListDialog::ListDialog): Hide "Select All" button when
in single-selection mode. Set "Ok" button as the default button, allows
Enter/Return to accept the selection. Handle double-click on list item with
the item_double_clicked slot. (ListDialog::item_double_clicked): New slot.
