tdf#130857 qt weld: Add QtInstanceCheckButton

Add a QtInstanceCheckButton as the native Qt
implementation for a weld::CheckButton.
This uses a QCheckBox.

Handle the "GtkCheckButton" object type from .ui
files in QtBuilder.

This will e.g. be needed for the "Insert" -> "Axes..."
dialog seen in Calc after a chart has been inserted
and double-clicked -- once further
remaining aspects needed to be able to support that dialog
has been implemented and it will be enabled
in QtInstanceBuilder::IsUIFileSupported.

The handling for the "inconsistent" state
is mostly based on the the VCL implementation,
see SalInstanceCheckButton::set_inconsistent etc.

QtInstanceCheckButton::QtInstanceCheckButton::set_label_wrap
remains unimplemented for now and triggers an assert,
can be implemented when adding support for a dialog
that actually makes use of it.
