avcodec/libjxlenc: support negative linesizes
libjxl doesn't support negative strides, but JPEG XL has an orientation
flag inside the codestream. We can use this to work around the library
limitation, by taking the absolute value of the negative row stride,
sending the image up-side-down, and telling the library that the image
has a vertical-flip orientation.
