video-scaler: add more ORC functions
...
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

video-scaler: rename resampler to video-resampler
...
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

video-scaler: remove color range argument
...
We just need to clip to the format limits, if there is extra headroom in
the range we can use that without problems.

vertical scaling functions.
