libhwjpeg: add support for setting custom horizontal padding per plane
Input buffers may already have horizontal padding applied (see
ImageFormat.YV12 for example). pa/2371678 and pa/2375202 adds
functionality to set horizontal padding in pixels through
VIDIOC_S_EXT_CTRLS. This CL updates V4L2 library.
Bug: 265156559
Test: checked output image when applying ag/20576841
