Make webots run in the Windows CI machine

Investigating why webots --sysinfo crashes in the Windows CI machines.

[omichel]

It turns out that the crash is due to OpenGL initialization:

webots/src/webots/gui/WbSingleTaskApplication.cpp

Lines 221 to 256 in 4afa988

	// create simply an OpenGL context
	QMainWindow mainWindow;
	QGLWidget glWidget(&mainWindow);
	mainWindow.setCentralWidget(&glWidget);
	mainWindow.show();
	// An OpenGL context is required there for the OpenGL calls like `glGetString`.
	// The format is QSurfaceFormat::defaultFormat() => OpenGL 3.3 defined in main.cpp.
	QOpenGLContext *context = new QOpenGLContext();
	context->create();
	QOpenGLFunctions *gl = context->functions(); // QOpenGLFunctions_3_3_Core cannot be initialized here on some systems like
	// macOS High Sierra and some Ubuntu environments.
	#ifdef _WIN32
	const quint32 vendorId = WbSysInfo::gpuVendorId(gl);
	const quint32 rendererId = WbSysInfo::gpuDeviceId(gl);
	#else
	const quint32 vendorId = 0;
	const quint32 rendererId = 0;
	#endif
	const char *vendor = (const char *)gl->glGetString(GL_VENDOR);
	const char *renderer = (const char *)gl->glGetString(GL_RENDERER);
	// cppcheck-suppress knownConditionTrueFalse
	if (vendorId == 0)
	cout << tr("OpenGL vendor: %1").arg(vendor).toUtf8().constData() << endl;
	else
	cout << tr("OpenGL vendor: %1 (0x%2)").arg(vendor).arg(vendorId, 0, 16).toUtf8().constData() << endl;
	// cppcheck-suppress knownConditionTrueFalse
	if (rendererId == 0)
	cout << tr("OpenGL renderer: %1").arg(renderer).toUtf8().constData() << endl;

	cout << tr("OpenGL renderer: %1 (0x%2)").arg(renderer).arg(rendererId, 0, 16).toUtf8().constData() << endl;

	delete context;
