AVFCameraViewfinderSettings - add NV12 format

Browse Source 
Add QVideoFrame::Format_NV12 (AVFoundation has kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange). Report it (set it) only if
it's supported by renderer's surface. Add bi-planar format support into CVPixelBufferVideoBuffer.
