tdf#130857 qt weld: Implement QtInstanceWidget::get_approximate_digit_width

Similar to how OutputDevice::approximate_digit_width, used
by SalInstanceWidget::get_approximate_digit_width does it,
get the width for all a text containing all of of the 10 digits
and divide by 10 to get the average/approximate width of a digit.

This method e.g. gets called by the print progress dialog.
