Resolution of util/locale_database/ are based on:
https://codereview.qt-project.org/c/qt/qtbase/+/294250
and src/corelib/{text,time}/*_data_p.h were then regenerated by
running those scripts.

Updated CMakeLists.txt in each of
	tests/auto/corelib/serialization/qcborstreamreader/
	tests/auto/corelib/serialization/qcborvalue/
	tests/auto/gui/kernel/
and generated new ones in each of

	tests/libfuzzer/gui/text/qtextdocument/setmarkdown/
	tests/libfuzzer/gui/text/qtextlayout/beginlayout/
by running util/cmake/pro2cmake.py on their changed .pro files.

Changed target name in
	tests/auto/gui/kernel/qaction/qaction.pro
	tests/auto/gui/kernel/qaction/qactiongroup.pro
	tests/auto/gui/kernel/qshortcut/qshortcut.pro
to ensure unique target names for CMake

Changed tst_QComboBox::currentIndex to not test the
currentIndexChanged(QString), as that one does not exist in Qt 6
anymore.

         To enable OpenGL rendering, you simply set a new QOpenGLWidget as the
         viewport of QGraphicsView by calling QGraphicsView::setViewport(). If

-        support (see QSurfaceFormat::samples()).
