libcamera: stream: Document stride will be 0 for compressed formats
For compressed formats, v4l2_pix_format.bytesperline value will be zero
and is documented similarly in the kernel. Since we set the stride to
v4l2_pix_format.bytesperline, document the case where it is expected
to be zero (i.e. if the format is compressed).
