tdf#130857 qt weld: Add QtInstanceImage skeleton Add a new class QtInstanceImage as a weld::Image implementation using native Qt widgets. It uses a QLabel that holds the Image, which can be set using QLabel::setPixmap [1]. This commit adds the new class, lets QtInstanceBuilder::weld_image return an instance of the new class, and extends QtBuilder to create a QLabel when it encounters a "GtkImage" object. The logic to actually set the image when either processing the .ui file or when one of the weld::Image::set_from_icon_name or one of the weld::Image::set_image variants gets called still needs to be implemented in subsequent commits for the label to actually display an image.

tdf#130857 qt weld: Implement QtInstanceImage::set_image Extract a helper to convert a BitmapEx to a QPixmap from the existing helper function `loadQPixmapIcon` and add a new helper that converts a css::uno::Reference<css::graphic::XGraphic>& to a QPixmap reusing most of the code. Use that to implement the QtInstanceImage::set_image variant with that parameter type. With this in place, opening the "Help" -> "About LibreOfficeDev" dialog in a WIP branch adding "cui/ui/aboutdialog.ui" to the list of .ui files in QtInstanceBuilder::IsUIFileSupported now opens the dialog with brand image and LibreOffice Community logo present, but other aspects in that dialog still need attention before enabling this by default.
