Fix deprecation warnings about QVariant API

Fix warnings like:
video/qvideosurfaceformat.cpp:522:47: warning: 'QVariant qVariantFromValue(const T&) [with T = QAbstractVideoBuffer::HandleType]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
video/qvideosurfaceformat.cpp:524:48: warning: 'QVariant qVariantFromValue(const T&) [with T = QVideoFrame::PixelFormat]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
video/qvideosurfaceformat.cpp:534:54: warning: 'QVariant qVariantFromValue(const T&) [with T = QVideoSurfaceFormat::Direction]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
video/qvideosurfaceformat.cpp:536:46: warning: 'QVariant qVariantFromValue(const T&) [with T = double]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
video/qvideosurfaceformat.cpp:538:53: warning: 'QVariant qVariantFromValue(const T&) [with T = QSize]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
video/qvideosurfaceformat.cpp:542:52: warning: 'QVariant qVariantFromValue(const T&) [with T = QVideoSurfaceFormat::YCbCrColorSpace]' is deprecated: Use QVariant::fromValue() instead. [-Wdeprecated-declarations]
