video-scaler: fix temp line allocation
...
We need to allocate the templine with the amount of pixels we are going
to handle, which we only know for the vertical resampler when we are
asked to resample.

video-scaler: add support for 16bits formats
...
Add scaler functions for 16 bits formats.
Rename the scaler functions so that 16bits versions don't look too
weird.
Remove old unused h_2tap functions
Fix v_ntap functions, it was using 1 tap too little.

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.
