avcodec/nvenc: Delay identification of underlying format of cuda frames
When input surfaces are cuda frames, we will not know what the actual
underlying format (nv12, p010, etc) is at surface allocation time.
On the other hand, we will know when the input frames are actually
registered and associated with a surface.
So, let's delay format discovery until registration time, which is
actually how we handle other frame properties, such as dimensions.
By itself, this change doesn't allow for transcoding of 10bit
content from cuvid, but it reduces the problem to the hardcoding of
the sw format in ffmpeg_cuvid.c

avcodec/cuvid: Restore initialization of pixel format in init()
I moved this into the handle_video_sequence callback because that's
the earliest time you can make an accurate decision as to what the
format should be.
However, transcoding requires that the decision between using
the accelerated PIX_FMT_CUDA vs a normal pix format happen at init()
time. There is enough information available to make that decision
and things work out with the underlying format only being discovered
in the sequence callback.
