fix(common): Changed QSV native format selector to:
  One luminance plane and one chrominance plane
fix(render): Now moving opengl context back to main thread after FallbackFrameMapper stops

Additionally, tweaked some things:
 - Made ``VAAPIDecoderImpl::getSwOutputFormat()`` nullptr-safe
 - Added an error message for unsupported ``Message::Action``s in ``Muxer::consume()``

 - PacketPadParams now contain the AVCodec* instead of just a AVCodecID
 - Implementations of IVideoEncoderImpl now must provide a way to get their AVCodec*
 - New ContainerFormat utility class to provide a way of getting a container format's capabilities
