tdf#130857 qt weld: Show help when help button clicked

Add special handling for the "Help" button in
QtInstanceDialog::handleButtonClick:

Don't close the dialog with the corresponding
response code, but instead request help, by
calling Help::Start with the widget's help ID
and QtInstanceWidget as parameters.

Together with the previous commit
