avformat/vvc: Don't use ff_copy_bits() There is no benefit in using it: The fast path of copying is not taken because of misalignment; furthermore we are only dealing with a few byte here anyway, so simply copy the bytes manually, avoiding the dependency on bitstream.c in lavf (which also contains a function that is completely unused in lavf).
