tdf#130857 qt weld: Implement "GtkExpander" equivalent
Extend QtExpander to provide what's needed
to implement the QtInstanceExpander methods.
Let QtInstanceBuilder::weld_expander return an
instance of the new class.
Signal handling still needs to be implemented
(calling `weld::Expander::signal_expanded` when
the expanded state is toggled).
QtInstanceExpander is e.g. needed by the "Set Password"
dialog. ("File" -> "Save As", check "Save with password"
checkbox and press "Save" to trigger the dialog.)
